Why are Narmada and Tapi considered different from most peninsular rivers?

Correct answer: They flow westward into the Arabian Sea

Direct answer: A, they flow westward into the Arabian Sea. Most large Peninsular rivers, such as the Mahanadi, Godavari, Krishna and Kaveri, flow eastward and generally form deltas on the Bay of Bengal coast. Narmada and Tapi are important exceptions: they flow west through rift valleys and enter the Arabian Sea, usually forming estuaries rather than large eastern deltas. A is correct. B is wrong because they do not originate in the Himalayas; they rise in the Peninsular region. C is wrong because it describes the common east-flowing pattern, not these two rivers. D is wrong because they do not form coral in the Andaman Islands; coral is a marine biological formation. Memory cue: Narmada and Tapi break the usual rule—westward to the Arabian Sea.
