Why is the Amarkantak Plateau considered a watershed region?
Answer and explanation
Correct answer: It is linked with the origins of rivers like Narmada and Son
The governing concept is a watershed, meaning a highland or divide from which drainage flows into different river systems. The Amarkantak Plateau is an important source region: the Narmada rises near Amarkantak and flows generally westward, while the Son originates in the same broad highland and flows eastward as a tributary system of the Ganga basin. This separation of drainage directions explains why option A is correct. The plateau is not merely a coastal site, as claimed in B; it is an inland highland. Option C incorrectly calls it a coral island, and D confuses it with a deltaic mouth. The key evidence is the origin and divergence of major rivers.
