Solution
The correct option is B Narmada and Tapti
Narmada and Tapi,
The west flowing rivers of the Peninsular India are fewer and smaller as compared to their east flowing counterparts.The two major west flowing rivers are the Narmada and the Tapi.This exceptional behavior is because these rivers didn’t form valleys and instead they flow through faults (linear rift, rift valley, trough) created due to the bending of the northern peninsula during the formation process of Himalayas.These faults run parallel to the Vindhyas and the Satpuras.The Sabarmati, Mahi and Luni are other rivers of the Peninsular India which flow westwards.Hundreds of small streams originating in the Western Ghats flow swiftly westwards and join the Arabian Sea.It is interesting to note that the Peninsular rivers which fall into the Arabian Sea do not form deltas, but only estuaries. {Fluvial Depositional Landforms}This is due to the fact that the west flowing rivers, especially the Narmada and the Tapi flow through hard rocks and hence do not carry any good amount of silt.Moreover, the tributaries of these rivers are very small and hence they don’t contribute any silt.Hence these rivers are not able to form distributaries or a delta before they enter the sea.
