Ganga river system tributaries MCQ - Practice Questions with Answers

The Son is a major right-bank tributary of the Ganga. It rises in central India, flows north-east, and joins the Ganga near Patna from the southern side, which makes it a right-bank tributary in the river-system classification. Ramganga, Gomti, and Ghaghara join the Ganga system from the northern side and are normally counted among its left-bank tributaries. Therefore, among the given rivers, Son alone fits the right-bank tributary description.

The Son River is a tributary of the Ganga. It originates near Amarkantak, flows through parts of central and eastern India, and joins the Ganga near Patna in Bihar. The Yamuna is a separate major tributary of the Ganga, but the Son does not drain into the Yamuna. Mahanadi is an independent east-flowing river system, and Narmada is a west-flowing peninsular river. Hence the river named in the question belongs to the Ganga system.
