The correct answer is: C. Sutlej
The Zanskar range is a mountain range in the Himalayas that runs along the eastern boundary of Himachal Pradesh. It is cut across by the Sutlej River, which flows from the Tibetan Plateau into India. The Sutlej is one of the five major rivers of the Punjab region. It is a tributary of the Indus River and is the longest river in Himachal Pradesh.
The other options are incorrect because they are not rivers that cut across the Zanskar range. The Ravi River flows through the state of Punjab in India. The Beas River flows through the states of Himachal Pradesh and Punjab in India. The Chenab River flows through the states of Jammu and Kashmir, Himachal Pradesh, and Punjab in India.
