Which is the incorrect pair ?

Question

Accepted Answer

The incorrect pair is Shivasamudram Dam - River Krishna. Here's why:

*   **Shivasamudram Dam - River Krishna (Incorrect):** The Shivasamudram Dam is built on the **Kaveri (Cauvery) River**, not the Krishna River. This makes the pairing factually incorrect. Shivasamudram is a significant hydroelectric power project in Karnataka, harnessing the power of the Kaveri River.

Now, let's explain why the other options are correct:

*   **Matatila Dam - River Betwa (Correct):** The Matatila Dam is indeed located on the Betwa River. This dam serves irrigation and power generation purposes in Uttar Pradesh and Madhya Pradesh.

*   **Bhakranangal Dam - River Sutlej (Correct):** The Bhakra Nangal Dam is a well-known dam built on the Sutlej River. It's a major multipurpose project providing irrigation and hydroelectric power to several states in northern India.

*   **Pong Dam - River Beas (Correct):** The Pong Dam, also known as the Beas Dam, is correctly paired with the Beas River. It's a significant earth-fill embankment dam used for irrigation and power generation in Himachal Pradesh.

Therefore, only the Shivasamudram Dam being associated with the Krishna River is factually wrong, making Option 2 the incorrect pair.
