Which among the following is a mature-phase Harappan site situated in the state of Rajasthan?

Kalibangan

The correct answer is Option 3- Kalibangan

Kalibangan is a mature-phase Harappan site situated in the state of Rajasthan.

The other three sites listed are all located outside of Rajasthan:

• Nageshwar is located in Gujarat.
• Manda is located in Jammu and Kashmir.
• Chanhudaro is located in Pakistan.

Kalibangan is located on the banks of the Ghaggar-Hakra River in the northern part of Rajasthan. It was one of the largest and most important Harappan sites in the region. Excavations at Kalibangan have revealed a well-planned city with a grid layout, a citadel, and a variety of public buildings, including a granary, a bathhouse, and a fire altar.

Kalibangan is also notable for its unique ploughed field, which is thought to have been used for agricultural purposes. The field is divided into seven equal plots by wooden furrows, which suggests that the Harappans were skilled in irrigation and agriculture.
