The correct option is B Indira Gandhi Canal
The Harike headworks feed the Rajasthan feeder canal, also known as the Indira Gandhi command canal. This canal carries water down to Rajasthan, providing water primarily for drinking and irrigation purposes. As a major river, Beas also has a few tributaries that feed water into this system. The major tributaries feeding into the Beas river are Parbati, Sukantari, Uhl, Sohan, and Kali Bein.
