Which river originates from the Amarkantak region?

Correct answer: Narmada

The direct answer is A, Narmada. Amarkantak is a highland region in Madhya Pradesh and is famous as the source area of the Narmada. To solve this, connect the place with the river: Narmada begins at Narmada Kund near Amarkantak and then flows generally westward through a rift valley to the Arabian Sea. Option A is correct because it is the river traditionally identified with the Amarkantak source. Option B, Ganga, is wrong because the Ganga system begins from Himalayan sources, especially the Bhagirathi at Gaumukh, not Amarkantak. Option C, Yamuna, is wrong because it rises from the Yamunotri Glacier in the Himalayas. Option D, Beas, is wrong because it originates in Himachal Pradesh near the Rohtang Pass area. A place can be connected with several local streams, but in standard school geography Amarkantak is a key source region for the Narmada. Memory cue: Amarkantak gives Narmada; Yamunotri gives Yamuna.
