Nagarjuna Sagar Dam is located on which river?

Correct answer: Krishna

The correct answer is Krishna. Nagarjuna Sagar Dam is a major multipurpose dam constructed across the Krishna River in the southern Deccan region. The project provides irrigation water and hydroelectric power and is important for agriculture in areas of present-day Telangana and Andhra Pradesh. Hence option A is correct. Godavari is another major peninsular river with separate projects, while Tungabhadra is a tributary of the Krishna and Kaveri belongs to a different river system. These similarities make the alternatives plausible, but they do not change the direct association of Nagarjuna Sagar with the Krishna. The key examination fact is the pair “Nagarjuna Sagar–Krishna River.”
