✓ Correct answer: a) 1 only
ExplanationThe Narmada River is unique among India’s major peninsular rivers due to its westward flow into the Arabian Sea, contrasting with the predominantly eastward flow of other large rivers in the region.Statement 1 is correct : The Narmada River flows through a linear rift valley which is a geological depression created by the subsidence of the Earth’s crust.It is flanked by the Vindhya Range to the north and the Satpura Range to the south.This rift valley naturally channels the river westward, distinguishing it from most other peninsular rivers that flow eastward.Statement 2 is incorrect : Though the Narmada does flow be- tween the Vindhya and Satpura ranges but it not the cause of its westward flow.The ranges themselves are remnants of older folded mountains.Statement 3 is incorrect : While most rivers in the Indian pen- insula flow eastward towards the Bay of Bengal.This is due to the region’s natural slope to the west from Central India.But the Narmada River’s westward course is dictated by its unique geological setting within a rift valley.240
