Size

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.

(15200) km is India's land boundary and shows land contact. Exam tip: understand the use of each figure.

Land boundary shows land contact and coastline shows maritime contact. Exam tip: study size with connectivity.

The (2.4%) share is important, but India is not the largest country. Exam tip: do not make wrong exaggerations from correct facts.

(3214) km shows north-south and (2933) km shows east-west extent. Exam tip: identify direction-based distances.

Rank and world share place India's size in global context. Exam tip: identify global comparison facts separately.

(3.28) million sq km is area, not coastline length. Exam tip: check both unit and meaning.

The correct area is about (3.28) million sq km. Exam tip: read the decimal place carefully.

(3214) km is north-south and (2933) km is east-west extent. Exam tip: remember number with direction.

Option A is correct because both the land boundary and the coastline are lengths, and both are expressed in kilometres. Their magnitudes can therefore be compared directly. In option B, area is in square kilometres while boundary length is in kilometres, so the units are different. Exam tip: before comparing two values, check that they represent the same physical quantity in the same unit.

Different measurements cannot be compared directly unless their units and meanings are understood. Square kilometres measure area, which covers a surface, while kilometres measure length or distance along a line. They are not the same kind of quantity. A value in million square kilometres therefore describes the size of an area, whereas a value in kilometres describes a distance such as length, width, or coastline.

Option C directly places 3.28 million square kilometres beside 3214 kilometres, so it compares unequal types of units. Options A, B, and D compare values that are all written in kilometres, even though their geographical meanings may differ. The educational point is not which number is larger, but whether the units represent comparable quantities. Hence C is correct.

Land boundary shows land contact and coastline shows maritime contact. Exam tip: read both as connectivity dimensions of size.

Coastline can be a base for maritime trade and port development. Exam tip: understand the economic use of coastline.

A long land boundary is important for administration and security. Exam tip: connect boundary figures with management.

A multidimensional understanding does not depend on one number alone. Area tells how much land India covers, rank places it in comparison with other countries, and land boundaries and coastline help explain its geographical connections and access. Each measure answers a different question, so combining them gives a fuller picture of India’s size and position.

Option A correctly assigns a separate meaning to each kind of information. The other choices mix up the roles of the figures. Rank does not measure coastline, area does not directly give the length of a land boundary, and an east–west distance does not express a percentage of area. The correct approach is to ask what each statistic actually measures before using it for comparison.

Area is actual measurement and rank is global comparison. Exam tip: connect measurement and comparison together.

(3214) km is north-south extent, not land boundary. Exam tip: identify the meaning of each number correctly.
