Which neighbouring country of India is near the Bay of Bengal?

Correct answer: Bangladesh

The direct answer is B, Bangladesh. The Bay of Bengal is the northeastern part of the Indian Ocean, beside the eastern coast of India and south of Bangladesh. The reasoning is: Bay of Bengal → eastern Indian Ocean → coastal Bangladesh. Option A, Maldives, is an island group in the Arabian Sea area, southwest of India, not near the Bay of Bengal. Option B, Bangladesh, is correct because its southern side opens toward the Bay of Bengal, and its rivers form a large delta there. Option C, Afghanistan, is a landlocked country to the northwest of the Indian subcontinent and has no coast on the Bay of Bengal. Option D, Nepal, is a landlocked Himalayan country north of India, so it also has no sea coast. A country may be called a neighbour even when the question asks about a nearby sea; here Bangladesh is the clear coastal answer. Memory cue: eastern sea of India means Bay of Bengal; Bangladesh lies beside it.
