Why is the Eastern Coastal Plain understood as wider than the Western Coastal Plain?

Correct answer: Large river deltas and wide plains occur on the eastern coast

The direct answer is A: large river deltas and wide plains occur on the eastern coast. The Eastern Coastal Plain lies between the Eastern Ghats and the Bay of Bengal. Large rivers such as the Mahanadi, Godavari, Krishna and Kaveri flow eastward and usually form broad deltas by depositing silt near their mouths. This makes the plain generally wider and more delta-rich than the Western Coastal Plain. Option A is correct because it gives the physical reason. Option B is wrong because Himadri is the highest Himalayan range, not a coastal plain. Option C is wrong because the Thar Desert is in north-western India and its dunes are not the Eastern Coastal Plain. Option D is wrong because Lakshadweep is an island group in the Arabian Sea, made mainly of coral, and is not the eastern mainland coast. Memory cue: east coast means big rivers, deltas and a broader plain; west coast means a narrower plain.
