India’s mainland starts from which latitude and extends northward?

Correct answer: 8°4′ N

The governing concept is the latitudinal extent of India’s mainland. The mainland stretches from approximately 8°4′ N in the south to about 37°6′ N in the north. Therefore, the southern starting latitude is 8°4′ N, making option A correct. The value 23°30′ N is associated with the Tropic of Cancer, which crosses the middle part of India, while 37°6′ N marks the northern limit of the mainland. The value 82°30′ E is a longitude used for Indian Standard Time, so it cannot answer a latitude question. Careful attention to N and E prevents confusion between latitude and longitude.
