Which option compares same units while comparing India's size?

Correct answer: (3214) km and (2933) km

The direct answer is A, 3214 km and 2933 km. The question asks which choice compares quantities in the same kind of unit. In option A, both figures are expressed in kilometres, so they can be compared directly as distances. Step by step: identify the unit of the first quantity; identify the unit of the second; check whether both units represent the same measurable kind; in A, both are km and both are distances. Option A is therefore correct. Option B mixes area, “3.28 million square km,” with distance, “15,200 km”; square kilometres and kilometres cannot be directly compared. Option C mixes a percentage with a distance, so the quantities are unlike. Option D mixes a rank, “seventh,” with an area, so neither unit nor meaning matches. The numbers in A need not describe the same direction; the key point is that both are comparable distance measurements. Exam cue: compare like with like.
