What is the geographical reason for considering the Western Coastal Plain narrow?

Correct answer: It is a limited strip between Western Ghats and Arabian Sea

Direct answer: A, it is a limited strip between the Western Ghats and the Arabian Sea. A coastal plain becomes narrow when a mountain range lies close to the coast. In western India, the Western Ghats run roughly parallel to the Arabian Sea, leaving only a small belt of low land between the mountains and the sea. A is correct. B is wrong because the Northern Plains lie south of the Himalayas and are not the Western Coastal Plain. C is wrong because the Brahmaputra delta belongs to the eastern region near the Bay of Bengal. D is wrong because the Andaman coral coast is an island feature, not the reason for the narrow mainland western coastal plain. Memory cue: Western Ghats close to the sea make the west coast narrow.
