Which figure should be identified as north-south distance in India's size?

Correct answer: 3214 km

The direct answer is B, 3214 km. India’s north-south extent is the distance from the northern part of the country to its southern mainland limit, and the standard school figure is about 3214 km. Option B is therefore correct. Option A, 2933 km, is India’s east-west extent, from the western side toward the eastern side, so it gives a different direction. Option C, 6100 km, is approximately the mainland coastline, not a straight directional spread across the country. Option D, 7516.6 km, is the total coastline figure including islands, not the north-south distance. The question asks for a directional distance, so first identify ‘north-south’, then select the matching number. There is no need to add or subtract the figures. The important pair is 3214 for north-south and 2933 for east-west. Memory cue: think of a vertical map arrow for 3214 and a horizontal arrow for 2933. Do not confuse national extent with boundary or coastline length.
