The Dul Hasti Hydroelectric Power Station is based on which one of the following rivers?

Introduction / Context:
This question is from Indian river-based power projects. Hydroelectric power stations are often asked in association with the rivers on which they are built. Dul Hasti is a major hydroelectric project in the Jammu and Kashmir region and forms part of India's utilisation of the waters of western rivers of the Indus system.

Given Data / Assumptions:
- The project mentioned is the Dul Hasti Hydroelectric Power Station.
- The options list Beas, Chenab, Ravi, Sutlej and Jhelum, all important rivers of the Indus basin.
- The aim is to identify the specific river on which Dul Hasti is built.
- We assume standard locations as used in exam-level geography.

Concept / Approach:
Dul Hasti Hydroelectric Project is located in the Kishtwar region of Jammu and Kashmir. It utilises the flow of the Chenab River, one of the major western tributaries of the Indus. Beas, Ravi, Sutlej and Jhelum also host various hydropower projects, but Dul Hasti is specifically associated with Chenab. The approach is to remember the mapping of major projects like Dul Hasti, Salal and Baglihar to the Chenab River.

Step-by-Step Solution:
Step 1: Recall that Chenab flows through the Jammu region of Jammu and Kashmir and is known for several hydroelectric projects.Step 2: Dul Hasti project is located in the Kishtwar area on the Chenab River.Step 3: Beas and Sutlej host other projects such as Pong Dam, Beas–Sutlej link and Bhakra, largely in Himachal Pradesh and Punjab.Step 4: Ravi and Jhelum also flow through Jammu and Kashmir but have different named projects.Step 5: Since Dul Hasti specifically corresponds to Chenab, select Chenab as the correct option.

Verification / Alternative check:
Lists of major hydroelectric projects in India clearly identify Dul Hasti as a project on the Chenab River. Government and power sector websites also describe Dul Hasti in technical documents that refer to the Chenab as the river source. Cross-checking with exam handbooks on rivers and dams confirms this mapping.

Why Other Options Are Wrong:
Beas: Hosts projects like Pong and Pandoh but not Dul Hasti.

Ravi: Associated with projects like Ranjit Sagar Dam, not Dul Hasti.
Sutlej: Known for Bhakra, Nathpa Jhakri and other projects, different from Dul Hasti.
Jhelum: Has its own set of hydroelectric stations but Dul Hasti is on Chenab.

Common Pitfalls:
Candidates may confuse various Indus tributaries because many hydropower projects exist in a relatively small mountainous region. Remembering at least one flagship project for each of the main western rivers helps: for example, Baglihar and Dul Hasti for Chenab, Uri for Jhelum, and Bhakra for Sutlej. This mental linking reduces the chance of mixing up rivers in such questions.

Final Answer:
Chenab
