Which river relation is most correct in considering Amarkantak a watershed?
Answer and explanation
Correct answer: Relation with sources of Narmada and Son
The governing concept is a watershed or water divide: a highland from which streams flow toward different drainage basins. Amarkantak is an important highland and source region in central India. The Narmada rises near Amarkantak and flows westward, while the Son rises in the same broader highland region and joins the Ganga drainage system eastward. This opposing drainage relationship explains option A. The mouth of the Ganga is a deltaic outlet, not an upland source; the Luni’s sandy areas are in western Rajasthan; and marine coral has no connection with Amarkantak’s watershed function.
