Rivers of peninsular India flowing towards Arabian Sea are _________.
A. Krishna-Kavery
B. Mahanadi-Mahi
C. Ganga-Jamuna
D. Narmada-Tapi

Hint:The Arabian Sea is a part or rather a north-western extension of the Indian Ocean. It is bounded between countries like India in the east, Oman in the west, Pakistan in the north and Yemen and Somalia in the southwest.

Complete answer:
Most of the major peninsular rivers flow from west to east and drain their waters into the Bay of Bengal, however, Narmada and Tapi which flow through the rift valleys empty themselves into the Arabian sea.Narmada river originates in the Amarkantak hills in Madhya Pradesh and flows west. It is joined by many small tributaries on its way through many states. Its basin covers parts of Madhya Pradesh and Gujarat. It covers a distance of about 1,312 km before it flows into the Arabian sea. It forms a 27 km long estuary and has a catchment area of about 98,796 sq. km.
Tapi river has its origin in the Satpura ranges in Madhya Pradesh and flows through the rift valley almost parallel to the Narmada. It is a much shorter river that covers parts of Madhya Pradesh, Gujarat and Maharashtra. It approximately covers a distance of 724 km before meeting the Arabian sea. It has a catchment area of 65,145 sq. km.

Hence, the correct answer is option (D).

Note:Both Narmada and Tapi being rift valley rivers do not accumulate alluvial and silt during their course through the valleys and hence don’t form any delta at their mouth of convergence with Arabian sea. However, they form estuaries. Mahi is another rift valley river that flows into the Arabian sea.
