Rivers and Lakes of India

The governing concept is the identification of tributaries belonging to a particular river basin. Kabini, also called Kapila in some references, is an important tributary of the Kaveri and joins the Kaveri in southern India. Hence option A is correct. Narmada is a separate west-flowing central Indian system; Gandak belongs to the Himalayan-Ganga network; and Luni is an inland-draining river of the Rajasthan region. The Kaveri system is commonly studied with tributaries such as Kabini, Hemavati, Harangi, and Shimsha. Recognising these tributary pairs helps distinguish the correct basin.

The governing concept is recognising tributary-main river pairs in the South Indian drainage system. Hemavati rises in the Western Ghats region of Karnataka and flows to join the Kaveri, making option B correct. Godavari has a different basin extending across central and southeastern India, while Tapi is a west-flowing river and Mahi drains toward the Gulf of Khambhat. The Kaveri system includes several notable tributaries, especially Hemavati, Kabini, Harangi, and Shimsha. Grouping these names with Kaveri helps avoid confusing them with rivers of the Godavari or western coastal drainage systems.

The governing concept is identifying a tributary through its downstream connection with a main river. The Amaravati is a southern Indian river that joins the Kaveri in Tamil Nadu, so option A is correct. The Yamuna belongs to the Ganga basin in northern India, Narmada flows westward through central India, and Brahmaputra belongs to the northeastern Himalayan drainage system. Similar names can cause confusion because Amaravati is also used for places, but the river itself is part of the Kaveri basin. Connecting the river with Tamil Nadu and the Kaveri is the key geographical clue.

The correct answer is Tamil Nadu because the Vaigai is a major peninsular river flowing through the southern part of that state. It rises in the Varusanadu Hills of the Western Ghats, flows eastward, and is closely associated with Madurai before reaching the Palk Strait region. Therefore, option A correctly identifies the state. Punjab and Haryana are linked mainly with northwestern river systems such as the Sutlej, Beas and Ghaggar, while Assam is associated with the Brahmaputra and Barak systems. The river’s course, basin and important city association make Tamil Nadu the unambiguous choice.

Option A is correct because the Pennar, also called the Penna, rises in the Nandi Hills area of Karnataka and flows mainly eastward through Andhra Pradesh before entering the Bay of Bengal. Its basin is therefore associated primarily with these two southern states. Punjab and Haryana belong to the northwestern drainage region, whereas Gujarat and Rajasthan are linked with rivers such as the Mahi, Sabarmati, Luni and Banas. Bihar and Jharkhand are part of the Ganga and Damodar-related drainage regions. The source-to-mouth route of the Pennar makes Karnataka and Andhra Pradesh the only suitable pair.

Ahmedabad is the correct answer because the Sabarmati River flows through the city and is an important part of its geographical and historical identity. The Sabarmati rises in the Aravalli region of Rajasthan and flows southwest through Gujarat before reaching the Gulf of Khambhat. Ahmedabad is especially well known for the Sabarmati riverfront and for the Sabarmati Ashram located beside the river. Patna is associated with the Ganga, Guwahati with the Brahmaputra, and Bhopal with lakes such as Upper Lake. These city-river relationships distinguish option A from the distractors.

Option A is correct: the Mahi River is noted for crossing the Tropic of Cancer twice. This unusual course results from the river’s looping path through parts of Madhya Pradesh, Rajasthan and Gujarat before it drains into the Gulf of Khambhat. The statement is a distinctive geographic fact used to identify the river in examinations. The Mahi is not the longest tributary of the Ganga, so option B is incorrect. It is a mainly rain-fed peninsular river rather than an entirely glacial river, ruling out C, and it reaches the sea rather than remaining an inland desert stream, ruling out D.

The Luni system is the correct answer. Sukri and Jawai are tributaries associated with the Luni drainage of western Rajasthan and adjoining areas. The Luni rises near the Aravalli region and flows through an arid landscape, where many channels are seasonal and their discharge is strongly dependent on rainfall. This explains why these rivers are studied as part of a desert or inland-drainage setting. The Godavari and Kaveri are major peninsular systems of central and southern India, while the Brahmaputra is a Himalayan river system of the northeast. Thus only option A fits both the tributaries and the desert-region clue.

The Gomti is a tributary of the Ganga, making option A correct. A tributary is a smaller river that joins a larger river and becomes part of its drainage basin. The Gomti rises in northern Uttar Pradesh, flows through important areas including Lucknow, and eventually joins the Ganga near Saidpur in Ghazipur district. This geographical relationship identifies the correct answer. Krishna is a major peninsular river, Sutlej belongs to the Indus system, and Narmada flows westward directly toward the Arabian Sea; none of these is the parent river of the Gomti. The key concept is to identify the larger river into which the tributary ultimately flows, rather than confusing it with another major Indian river.

Yamuna is the correct answer because the Hindon is a tributary of the Yamuna in western Uttar Pradesh. It originates in the Shivalik foothills and flows through the region around Saharanpur, Muzaffarnagar and Ghaziabad before joining the Yamuna near Delhi. This local-to-larger river connection is the governing concept in the question. Narmada is a west-flowing peninsular river, Teesta is associated with the Brahmaputra system in the eastern Himalaya, and Kaveri is a southern peninsular river. Their locations and drainage basins do not match the Hindon, so option A is unambiguous.

The Yamuna is the correct answer. The Ken is a major river of the Bundelkhand region and joins the Yamuna near Chilla in Uttar Pradesh. Since the Yamuna itself is one of the principal tributaries of the Ganga, the Ken is part of the larger Ganga drainage system through the sequence Ken to Yamuna to Ganga. The Brahmaputra is an eastern Himalayan river, Godavari is a large peninsular river flowing toward the Bay of Bengal, and Tapi flows westward into the Arabian Sea. These drainage patterns rule out the other options and confirm B.

The Ganga system is the correct answer through a sequence of tributary relationships. The Rihand, also known as the Renu or Rehand in some references, is a tributary of the Son River. The Son then joins the Ganga near Patna, so the chain is Rihand to Son to Ganga. This step-by-step drainage logic explains why the Rihand belongs to the Ganga basin even though it does not directly join the Ganga. The Kaveri and Mahi are separate peninsular systems, while the Indus system drains toward the northwest. Hence option A is the only appropriate answer.

The correct answer is Sankh and South Koel. The Brahmani is an important east-flowing river of peninsular India, and its main headstream is formed in the Chota Nagpur Plateau region by the meeting of the Sankh and South Koel rivers. After entering Odisha, the Brahmani flows generally south-eastward and eventually reaches the Bay of Bengal through its deltaic and estuarine channels. Option B is incorrect because Bhaga and Chandra unite to form the Chandrabhaga, or Chenab, in the Himalayas. Option C refers to rivers associated with the Pune region, while Option D describes the formation of the Ganga at Devprayag. Thus, option A correctly identifies the tributaries that form the Brahmani.

The correct answer is Odisha. The Baitarani is one of the important rivers of eastern India and flows mainly through Odisha before reaching the Bay of Bengal. In school geography, it is commonly studied with the Mahanadi and Brahmani as part of Odisha’s coastal drainage network. The river supports fertile alluvial areas but can also contribute to floods during intense monsoon rainfall. Gujarat is associated with rivers such as the Narmada, Tapi and Sabarmati; Kerala has short west-flowing rivers such as Periyar and Bharathapuzha; and Goa is drained by smaller west-flowing rivers including the Mandovi and Zuari. These geographical associations eliminate options B, C and D. Therefore, option A is the only correct answer.

The correct answer is Odisha. The Rushikulya is a coastal river of Odisha that flows eastward and empties into the Bay of Bengal. It is notable in regional geography because it is a relatively short peninsular river and is associated with the coastal plain of southern Odisha. The wording already gives the direction and outlet, so the key task is to connect the river with its state. Haryana and Punjab are inland northwestern states and do not have a river of this name reaching the Bay of Bengal. Rajasthan is also inland and is better associated with drainage features such as the Luni, which moves toward the Rann of Kachchh. Consequently, options B, C and D conflict with the river’s location, while option A correctly identifies its state.

The correct answer is Krishna. The Koyna rises in the Western Ghats of Maharashtra and joins the Krishna River, making it an important tributary in the Krishna drainage system. The Koyna region is also associated with the Koyna Dam and reservoir, but the question asks about the river relationship rather than the project. The Ganga belongs to the northern Himalayan drainage system, and Jhelum is a major tributary of the Indus associated with Kashmir. Luni is an inland-draining river of western Rajasthan and does not belong to the Krishna basin. The physical setting therefore provides a useful check: Koyna is a peninsular, west-Ghat river, while Krishna is a major east-flowing Deccan river. Hence option A is correct.

The correct answer is Godavari. The Pranhita is a major tributary of the Godavari and is formed by the confluence of the Wainganga and Wardha rivers. It contributes a very substantial share of the Godavari’s water and is therefore important when studying the drainage network of peninsular India. The river is associated with the Maharashtra–Telangana region and ultimately carries its water into the Godavari system. Kaveri is a separate southern peninsular basin, while Narmada flows westward into the Arabian Sea and does not receive the Pranhita. Sabarmati is another west-flowing river of western India. These basin differences make the alternatives distinguishable. Therefore, option A correctly names the larger river system.

The correct answer is the Godavari river system. The Indravati rises in the Eastern Ghats region and flows through parts of Odisha and Chhattisgarh before joining the Godavari in Telangana. It is one of the important tributaries of the Godavari and is especially associated with the Bastar plateau and adjoining areas. The Yamuna belongs to the Ganga system of northern India, while the Sutlej is part of the Indus system and has a Himalayan course. The Mahi is a separate west-flowing river that reaches the Gulf of Khambhat. Since Indravati is a peninsular tributary that ultimately joins the Godavari, option A is the only geographically correct choice.

The correct answer is Godavari. The Manjira is an important tributary of the Godavari and flows through the Deccan region, particularly across parts of Maharashtra, Karnataka and Telangana. It joins the Godavari near Kandakurthi, making it useful for identifying the internal structure of the Godavari basin. Kaveri is a separate river system of southern India, while Narmada flows westward through a rift valley and reaches the Arabian Sea. Chenab is a Himalayan river and an important tributary of the Indus system. Their locations and drainage directions are different from those of the Manjira. Thus, the basin relationship clearly supports option A.

The correct answer is Godavari. The Purna is generally identified as a tributary of the Godavari and belongs to the peninsular drainage system of western and central India. It should not be confused with rivers that have similar names in other parts of the country. The Brahmaputra is a major Himalayan river of the northeast, while Jhelum is a Himalayan tributary of the Indus system. Gandak is another Himalayan tributary that joins the Ganga in the northern plains. The Purna’s association with the Godavari is established by its basin location and connection with the Deccan drainage network. Therefore, option A is correct, whereas options B, C and D belong to distinct northern river systems.
