Which one of the following rivers cuts across all the three ranges of the Himalayas ?

Ravi
Sutlej
Chenab
Jhelum

The correct answer is (b), Sutlej.

The Sutlej is a river in northern India and Pakistan. It is one of the five rivers of Punjab, and the longest of the five rivers that flow into the Indus River. The Sutlej originates in the Garhwal Himalayas in the Indian state of Himachal Pradesh. It flows through the states of Punjab and Haryana in India, and then into Pakistan, where it joins the Indus River near Mithankot. The Sutlej is a major source of irrigation water for the Punjab region. It is also a popular destination for white-water rafting and other water sports.

The other options are incorrect because they do not cut across all three ranges of the Himalayas. The Ravi River originates in the Pir Panjal Range of the Himalayas and flows through the Indian states of Himachal Pradesh and Punjab. The Chenab River originates in the Zanskar Range of the Himalayas and flows through the Indian states of Jammu and Kashmir and Punjab. The Jhelum River originates in the Pir Panjal Range of the Himalayas and flows through the Indian state of Jammu and Kashmir and Pakistan.
