Tawa River is a tributary of which major river?

Correct answer: Narmada

A tributary is a smaller river that joins a larger river. The Tawa is an important river of central India and joins the Narmada, so it belongs to the Narmada river system. This relationship is also useful when studying the Tawa Dam and the geography of Madhya Pradesh. The question asks for the major river receiving the Tawa’s flow.

The correct choice is A, Narmada. The Ganga, Krishna, and Kaveri are major river systems, but Tawa is not their tributary. A useful memory link is “Tawa–Narmada”: the Tawa contributes its water to the Narmada before the larger river continues its course toward the Arabian Sea. Thus the drainage-system match clearly supports option A.
