Which of the following rivers is the primary right-bank tributary of the Ganga River originating from the Amarkantak plateau?

💡 Solution & Explanation

The Son River originates near the Amarkantak plateau in Madhya Pradesh and flows in a northward direction before joining the Ganga River as a major right-bank tributary just upstream of Patna. It forms a wide valley and drains parts of central and eastern India. Other tributaries like the Gandak and Kosi join the Ganga from the northern left bank originating in the Himalayas. Indian river systems and their tributary networks are essential geographical knowledge.
