Size

All three facts show India's size in a global context. Exam tip: study area, rank and percentage together, not separately.

Seventh rank means six countries are larger than India. Exam tip: learn to derive the number of larger countries from rank.

(15200) km is land boundary while (7516.6) km is total coastline. Exam tip: keep the names of both lengths correct.

The two figures describe distances in different directions across India. The north–south extent is 3214 km, while the east–west extent is 2933 km. Comparing the numbers directly shows that 3214 is larger than 2933. The difference is 281 km, so the north–south length is greater, although the two measurements are fairly close.

Thus, option D is correct: India’s north–south extent is slightly greater. Option A reverses the comparison. The other choices do not describe the figures at all: neither measurement is zero, and a distance across the country is not the same thing as a coastline. The important method is to match each number with its direction before comparing the values.

3.28 million sq km measures India’s total area because square kilometres are units of area. 7,516.6 km refers to the length of India’s coastline, while 15,200 km refers to the length of its land boundary; both are length measurements, not area measurements. Exam tip: identify square kilometres for area and kilometres for distance or boundary length.

The direct answer is option B: 2.4% tells us India's share in the total geographical area of the world. To understand this, a percentage means a part out of 100. India occupies about 2.4 parts out of every 100 parts of the world's land area. This figure describes area, not a distance or a rank. Option A is wrong because coastline is measured in kilometres, not by this percentage. Option B is correct because it directly states India's share of world geographical area. Option C is wrong because land boundary is a length measured in kilometres. Option D is wrong because north-south extent is also a distance measured in kilometres. The reasoning is therefore: the unit is percent, the idea is a share, and the subject is world area. Memory cue: percent means share; kilometres mean distance.

Land boundary is a length, so it is measured in km, not square km. Exam tip: choose the answer by checking the unit.

Due to large size, natural conditions differ in different regions. Exam tip: treat size as a cause of diversity.

Total coastline includes the coastline of mainland and islands. Exam tip: remember total coastline with islands.

(15200) km land boundary shows land contact with neighbours. Exam tip: do not mix land boundary with coastline.

7,516.6 km is the length of India’s total coastline, where the land meets the sea. A land boundary is shared with neighbouring countries and is about 15,200 km in total, so option B does not describe this figure. Exam tip: remember 7,516.6 km for coastline and about 15,200 km for land boundary.

Russia, Canada and China are larger than India in area. Exam tip: separate larger countries from smaller neighbours.

Nepal and Bhutan are neighbouring countries smaller than India in area. Exam tip: keep neighbour comparison and world rank comparison separate.

This statement shows that large size causes diversity. Exam tip: look at the effect along with the fact.

These figures are north-south and east-west distances. Exam tip: keep direction-based extent and coastline separate.

In a large size, needs of different regions differ. Exam tip: connect size with administrative planning.

A long coastline is linked with maritime trade, fishing and ports. Exam tip: connect coastline with economic activities.

Land boundary is linked with neighbouring countries and is important in political geography. Exam tip: connect (15200) km with land boundary.

This option connects area and land boundary with correct units and meanings. Exam tip: identify the category of each figure.

(2.4%) is India's share in world area, not east-west extent. Exam tip: do not treat percentage as directional distance.

A country’s area is a strong way to compare its physical size with that of other countries. India covers about 3.28 million square kilometres, making it one of the world’s largest countries by area. It is commonly ranked seventh in the world by total area, after Russia, Canada, the United States, China, Brazil, and Australia, depending on the measurement convention used. These numerical facts give objective support to the idea that India is vast.

Option A is correct because it combines a measured area with an international rank. The unit “million square kilometres” is important: 3.28 million square kilometres represents a very large territory. The other options either give no evidence or make clearly false claims. India does have a coastline, its area is known, and it is not the world’s smallest country. Area and rank together are stronger evidence than a vague statement, so option A best establishes India’s vastness.

Land boundary is (15200) km and total coastline is (7516.6) km. Exam tip: compare lengths with the same unit.

Area measures the surface covered by a place, so it has two dimensions: length and breadth. When these dimensions are multiplied, the unit becomes square kilometres, written as km² or sq km. India’s area is therefore expressed as 3.28 million square kilometres. Writing only million km gives a unit of length, not a unit of surface area, so the measurement is incomplete and potentially misleading.

Option A is correct because area requires square kilometres. Percent is a way of showing a share and is not the necessary unit for every area measurement. A kilometre does not show rank; it measures distance. India certainly has an area, so option D is plainly false. The essential rule is to use ordinary kilometres for distance and square kilometres for area.

(2.4%) is comparative share and (3.28) million sq km is actual measurement. Exam tip: keep percentage and measurement separate.

The direct answer is option B: 15,200 km is associated with India's land boundary and its land contact with neighbouring countries. A boundary is the line separating one country from another, so it is measured in kilometres. India has a very long land boundary with several neighbouring countries; this figure helps describe its size and geographical contacts. Option A is wrong because 3,214 km is not the standard total length of India's coastline; the coastline is about 7,516.6 km including islands. Option B is correct because 15,200 km is the commonly taught length of India's land frontier, and it relates to land neighbours. Option C is wrong because 2.4% expresses India's share of world area, not east-west distance. Option D is wrong because seventh rank refers to India's position by area, not coastline length. Exam cue: match each number with its unit and meaning.
