Choose the word which is different from the rest.

Mettur
Aswan
Hirakud
Sutlej E. Pong

The answer is D. Sutlej.

Mettur, Aswan, Hirakud, and Pong are all dams. A dam is a barrier constructed to hold back water. Dams are used for a variety of purposes, including irrigation, flood control, and hydroelectric power generation.

The Sutlej is a river in India and Pakistan. It is one of the five rivers of Punjab. The Sutlej is a tributary of the Indus River.

The other four options are all dams. Mettur Dam is a dam on the Kaveri River in Tamil Nadu, India. Aswan Dam is a dam on the Nile River in Egypt. Hirakud Dam is a dam on the Mahanadi River in Odisha, India. Pong Dam is a dam on the Beas River in Himachal Pradesh, India.

The Sutlej is different from the other options because it is a river, not a dam.
