Which of the following canals has been taken out from Damodar River?

The correct answer is B) Eden Canal. It is a Damodar river canal in West Bengal, built during the British period and named after Ashley Eden, the then Lieutenant Governor of Bengal. Its headworks draw water from the Damodar, and the river's flow is regulated today by the Durgapur Barrage (1955) and the Damodar Valley Corporation (1948) reservoirs.

• A) Sirhind Canal is wrong. It is fed by the Sutlej at Ropar headworks in Punjab, not by the Damodar.
• C) Bist Doab Canal is wrong. It lies in the Punjab doab between the Sutlej and Beas, so it is linked to those rivers, not the Damodar.
• D) Eastern Gray canal is a distorted name. The Eastern Ganga Canal (Ganga system) is the nearest real canal, and it is not a Damodar canal.

The core concept is river-canal mapping: which canal system belongs to which river. This ties into the Prelims geography of Indian rivers and irrigation, and into Mains GS-1 and GS-3 themes on multipurpose river valley projects such as DVC.

Trap: aspirants mix up Punjab and Bengal canals because they all sound similar. Map each canal to its river, not to the state where it is famous.
