Which of the following archaeological sites has evidence of pit-dwellings?

Burzahom

The correct answer is Option 2- Burzahom

Burzahom archaeological site has evidence of pit-dwellings.

The other three options, Mehrgarh, Rana Ghundai, and Palavoy, also have evidence of other types of dwellings, but pit-dwellings have only been found at Burzahom.

Pit-dwellings are semi-subterranean dwellings that were used by many different cultures around the world. They are typically constructed by digging a pit into the ground and then covering it with a roof made of wood, earth, or other materials. Pit-dwellings offer a number of advantages, such as insulation from the elements, protection from predators, and storage space.

The pit-dwellings at Burzahom date back to the Neolithic period, around 3000 BC. They are circular or oval in shape and range in size from 2 to 8 meters in diameter. The walls of the pit-dwellings are lined with stones and the floors are covered with earth. The roofs were likely made of wood and thatch.

The discovery of pit-dwellings at Burzahom provides important insights into the lives of early people in the Kashmir Valley. The pit-dwellings suggest that the people of Burzahom were a settled community who relied on agriculture and animal husbandry for their livelihood.
