The correct answer is C. Siswal.
Siswal is a village in the Kurukshetra district of Haryana, India. It is located about 15 kilometers from Kurukshetra city. The village is known for its archaeological site, which has yielded evidence of agriculture from the Neolithic period. The site was excavated in the 1960s by the Archaeological Survey of India. The excavations revealed a number of tools and artifacts made of stone, bone, and pottery. These artifacts date back to the period between 6000 and 3000 BCE. The evidence from Siswal suggests that agriculture was already being practiced in Haryana by the Neolithic period. This is significant because it shows that agriculture was not just a practice of the Indus Valley Civilization, but was also practiced in other parts of India at the same time.
The other options are incorrect. Sirsa is a city in the Sirsa district of Haryana. Hisar is a city in the Hisar district of Haryana. Kurukshetra is a city in the Kurukshetra district of Haryana. There is no evidence of agriculture from the Neolithic period at any of these places.
