The direct answer is B: the Jhelum belongs to the Indus river system. A river system includes a main river and its tributaries that drain a common area. The Jhelum rises in the Kashmir region, flows through the valley, and joins the Chenab; the Chenab is an important tributary within the Indus system. Therefore the fact chain is: Jhelum joins Chenab, Chenab belongs to the Indus network, so Jhelum is part of the Indus system. Option A, Kaveri, belongs to the east-flowing peninsular river system and reaches the Bay of Bengal. Option B is correct: Jhelum is one of the major rivers associated with the Indus system. Option C, Godavari, is a major peninsular river flowing eastward to the Bay of Bengal. Option D, Mahanadi, is also an east-flowing peninsular river, not an Indus tributary. Memory cue: remember the Indus group as Indus, Jhelum, Chenab, Ravi, Beas, and Sutlej.

The direct answer is D: Mahanadi. Hirakud Dam is built across the Mahanadi River in Odisha. It is one of India’s important multipurpose river projects, helping with water storage, irrigation, flood control and hydroelectric power. Step by step: identify Hirakud as a major dam in Odisha; recall the river flowing through that region; match it with Mahanadi. Option D is correct because Hirakud and Mahanadi are a standard geography pair. Option A, Godavari, is wrong because although it is a major peninsular river, Hirakud is not built on it. Option B, Narmada, is wrong because major dams such as Sardar Sarovar are associated with the Narmada. Option C, Krishna, is wrong because it is a separate southern river system with different dams. The location clue is useful: Hirakud in Odisha should immediately bring Mahanadi to mind. Memory cue: ‘Hirakud–Mahanadi–Odisha.’

The direct answer is B: Sambhar Lake is a saltwater lake associated with salt production. It is an inland saline lake in Rajasthan. Water entering the basin evaporates strongly in the dry climate, while dissolved salts remain behind and become concentrated. This natural condition supports the production and collection of salt, giving Sambhar major geographical and economic importance. Option B is correct because it includes both the lake’s saline nature and its connection with salt production. Option A is wrong: Sambhar is not a glacial lake formed by melting mountain ice. Option C is wrong: it is not located in the Godavari Delta; that delta lies in eastern coastal India. Option D is wrong in two ways: Sambhar is not a freshwater river, but a saline lake. Also, a lake and a river are different types of water bodies. The key contrast is saline versus freshwater. Memory cue: “Sambhar = Rajasthan + salt.”
