Correct option is A

Introduction
The southernmost point of the Indian Union is the Indira Point, which is located in the Great Nicobar Island of the Andaman and Nicobar Islands. Its geographical coordinate is approximately 6° 45' N latitude. Note that the mainland's southernmost point is Cape Comorin (Kanyakumari) at 8° 4' N, but the question asks for the boundary in the Bay of Bengal, which includes the islands.
