Which two rivers are involved in the formation of Chenab River?

Correct answer: Chandra and Bhaga

The direct answer is B: Chandra and Bhaga. The Chenab is a major river of the Indus river system. In the Himalayan region of Himachal Pradesh, the Chandra River and the Bhaga River meet at Tandi. After this confluence, the combined river is called the Chandrabhaga or Chenab. Step by step: identify the river asked about; recall that Chenab has two headstreams; identify those headstreams as Chandra and Bhaga; then place the river in the Indus system. Option A, Bhima and Amaravati, does not form the Chenab and belongs to peninsular river geography. Option C, Kali and Sharda, refers to rivers associated with the Kali or Mahakali system, not the Chenab. Option D, Luni and Banas, concerns rivers of western India and does not form the Chenab. Memory cue: Chandra plus Bhaga gives Chandrabhaga, later called Chenab.
