Which river forms its delta on the eastern coastal plain?

Kaveri

The Kaveri is one of the important rivers flowing eastward across southern India. It enters the eastern coastal plain and builds the Kaveri delta before reaching the Bay of Bengal. A delta develops where a river slows down near its mouth and deposits the sediments carried from inland areas. Thus, option A, Kaveri, is correct. Narmada, Tapi, and Mahi are west-flowing rivers that generally reach the Arabian Sea, so they do not fit this question.

The easiest method is to connect east-flowing rivers with deltas on India’s eastern coastal plain. The Kaveri flows through Karnataka and Tamil Nadu, then spreads into distributaries in the fertile delta region of Tamil Nadu. This is also associated with the Coromandel Coast. By contrast, the Narmada, Tapi, and Mahi flow toward the western coast. Therefore, the supplied answer A is supported by the river’s direction and landform formation.
