The correct answer is: A. Chenab river.
The Salal hydroelectric project is a run-of-the-river hydroelectric power station on the Chenab River in the Indian state of Jammu and Kashmir. The project was commissioned in 1984 and has a installed capacity of 900 MW.
The Chenab River is one of the five major rivers of the Indus River basin. It originates in the Pir Panjal Range in the Indian state of Jammu and Kashmir and flows through the Indian state of Himachal Pradesh and the Pakistani province of Punjab before joining the Indus River near Attock. The Chenab River is a major source of irrigation and hydroelectric power for both India and Pakistan.
The other options are incorrect because:
- The Ravi River is a tributary of the Chenab River.
- The Indus River is the largest river in Pakistan.
- The Jhelum River is a tributary of the Indus River.
