Which option correctly links coast, water body and physiographic division?

Correct answer: पश्चिमी तट / अरब सागर / पश्चिमी तटीय मैदान / West coast / Arabian Sea / Western Coastal Plain

The direct answer is A: west coast, Arabian Sea, Western Coastal Plain. To solve this, match the three facts in order: the west coast of India faces the Arabian Sea, and the plain along that coast is called the Western Coastal Plain. Option A is correct because all three parts agree. Option B is wrong in two ways: the east coast faces the Bay of Bengal, not the Arabian Sea, and the eastern coast is associated with the Eastern Coastal Plain, not the Western Coastal Plain. Option C is wrong because the west coast does not face the Bay of Bengal, and the Eastern Coastal Plain belongs to the east coast. Option D is wrong because the Himalayas are a mountain system, not a coast; also, the Arabian Sea and island groups do not create the stated correct three-part relationship. A useful map check is to place India between the Arabian Sea on the west and the Bay of Bengal on the east. Memory cue: west–Arabian–Western; east–Bay of Bengal–Eastern.
