The correct answer is: a) Neolithic pit dwellings.
Burzahom is an archaeological site located in the Srinagar district of Jammu and Kashmir, India. It is one of the earliest known human settlements in the Kashmir Valley. The site has been dated to the Neolithic period, and is known for its well-preserved pit dwellings.
The pit dwellings at Burzahom are circular in shape, and are about 3 meters in diameter. They were built by digging a pit into the ground, and then lining the walls with stone slabs. The roofs of the dwellings were made of thatch.
The pit dwellings at Burzahom provide valuable insights into the lives of the early inhabitants of the Kashmir Valley. They show that the people were skilled in building and construction, and that they had a sophisticated understanding of the environment.
The other options are incorrect because:
- Megalithic burial structures are not found at the Burzahom archaeological site.
- Buddhist monasteries are not found at the Burzahom archaeological site.
- Mughal-era forts are not found at the Burzahom archaeological site.
