With reference to the Indus River system, of the following four rivers, three of them pour into one of them which joins the Indus direct. Among the following which one is such river that joins the Indus direct?
Explanation
The drainage network of the eastern tributaries of the Indus River system converges hierarchically in Pakistan before meeting the main stem:
– The Jhelum joins the Chenab near Jhang in Pakistan.
– The Ravi empties into the Chenab near Sarai Sidhu.
– The collective unified waters of the Jhelum, Ravi, and Chenab then join the Sutlej River at Uch Sharif, forming the historic Panjnad (‘Five Rivers’).
– The Sutlej River, carrying this collective unified discharge, flows southwestward to directly empty into the Indus River a few kilometres upstream of Mithankot.
Hence, the river that directly joins the Indus is the Sutlej — Option D.
