Among the following tributaries, which one is the part of the Ganga river basin?

Explanation

The North Koel River flows in Jharkhand and is a tributary of the Son River, which joins the Ganga near Patna. The South Koel River flows through Jharkhand and Odisha and, after joining the Shankh River near Rourkela, flows as the Brahmani River. The Barakar River is the main tributary of the Damodar River, which ultimately joins the Hooghly in the lower Ganga Basin. The Damodar River Basin is a sub-basin of the Ganga River Basin. Hence, more than one river listed is part of the Ganga River Basin.
