Answer 1

The Correct Option is A

Step 1 — About the river Sone:
The river Sone (or Son) is one of the major rivers in central and eastern India. It originates near Amarkantak in Madhya Pradesh, which is also the source region for the Narmada and Mahanadi rivers. The Sone flows north-eastwards through Madhya Pradesh, Uttar Pradesh, Jharkhand, and Bihar.

Step 2 — Course of the river:
After rising from the Maikal Hills, the Sone flows through valleys and plateaus, covering a length of about 784 km. It is known for its wide sandy bed and seasonal flow variations. The river carries significant water during the monsoon but reduces drastically in the dry season.

Step 3 — Confluence with the main river:
The Sone ultimately joins the Ganga River near Patna in the state of Bihar. This makes it one of the important southern tributaries of the Ganga, contributing significantly to the Ganga basin.

Step 4 — Conclude:
Thus, the river Sone is a tributary of the Ganga.

Answer: The correct option is (A) : Ganga.
