Which river system rises near Amarkantak and flows westward through a rift valley to meet the Arabian Sea?
Answer and explanation
Correct answer: Narmada river system
The governing geographical concept is the distinction between major east-flowing and west-flowing peninsular river systems, together with the structural control of rift valleys. The Narmada rises near Amarkantak in Madhya Pradesh, follows a westward course through a tectonic rift valley, and drains into the Arabian Sea through the Gulf of Khambhat region. Hence option A is correct. Godavari, Mahanadi and Krishna generally flow eastward across the Deccan and ultimately reach the Bay of Bengal, so they do not fit the complete combination of source region, westward direction, rift-valley course and Arabian Sea outlet.
