Question

The river Sone is a tributary of which one of the following rivers?

• A. Ganga
• B. Yamuna
• C. Narmada
• D. Mahanadi

Hint:

It joins this river near Danapur, close to Patna.

Answer 1

The Correct Option is A

This question asks which major river the Son (Sone) river feeds into. Reviewing the options helps rule out the wrong ones.

1. Ganga: The Son, originating near Amarkantak, travels roughly 780 km and merges with the Ganga near Danapur close to Patna, Bihar, making it one of the Ganga's important right bank tributaries.
2. Yamuna: The Yamuna is itself a tributary of the Ganga and does not receive the Son's waters.
3. Narmada: This river flows west into the Arabian Sea and has no confluence with the Son.
4. Mahanadi: This river flows through Odisha into the Bay of Bengal, an entirely separate system from the Son.

Since the Son joins the Ganga near Patna, option A is correct.
