Between which latitudes does mainland India extend?

Correct answer: 8°4′ N to 37°6′ N

The governing concept is the latitudinal extent of mainland India. Its mainland stretches from about 8°4′ north latitude in the south to 37°6′ north latitude in the north, so option A is correct. Both limits are north of the Equator, which immediately rules out options B and C. Option D places India much farther north than its actual position. The order also matters: 8°4′ N is the southern limit and 37°6′ N is the northern limit. Island groups may extend farther south, but they are excluded because the question specifically says mainland India.
