8°4'N
Explanation
The latitudinal extent of India is defined by two distinct southern points: one for the mainland and one for the entire territory of the Indian Union, which includes the island groups.- 8°4'N: This is the southernmost latitude of the Indian mainland. It corresponds to Kanyakumari (Cape Comorin) in Tamil Nadu, where the Arabian Sea, the Bay of Bengal, and the Indian Ocean meet.
- 6°4'N: This represents the southernmost point of the Indian Union, known as Indira Point (formerly Pygmalion Point). It is located in the Great Nicobar Island of the Andaman and Nicobar archipelago.
- 37°6'N: This is the northernmost latitude of India, located at Indira Col in the trans-Himalayan region.
- 23°30'N: This corresponds to the Tropic of Cancer, which passes through the middle of the country, dividing it into the tropical southern half and the subtropical northern half.
Key Takeaway: Candidates must carefully distinguish between the "southernmost point of the mainland" (8°4'N) and the "southernmost point of the Indian Union" (6°4'N).
