The correct answer is: a) Adichanallur.
Adichanallur is a village in the Tirunelveli district of Tamil Nadu, India. It is a well-known archaeological site, with evidence of human habitation dating back to the Paleolithic period. The site has yielded a number of important artifacts, including stone tools, pottery, and human remains.
Adichanallur is located on the banks of the Vaigai River. The site was first excavated in the 1870s by the British archaeologist Robert Bruce Foote. Foote found a number of stone tools at the site, which he dated to the Paleolithic period.
In the 1960s, the Indian Archaeological Survey conducted further excavations at Adichanallur. These excavations revealed a number of important artifacts, including pottery, human remains, and a number of stone tools. The pottery found at Adichanallur is similar to that found at other Paleolithic sites in India, such as Bhimbhetka and Patne.
The human remains found at Adichanallur are also of great importance. These remains show that the people who lived at Adichanallur were of a different race than the people who lived in the area at the time of the Indus Valley Civilization. This suggests that the people of Adichanallur may have been the ancestors of the modern-day Tamil people.
The stone tools found at Adichanallur are also of great importance. These tools show that the people of Adichanallur were skilled in the use of stone. The tools found at Adichanallur include axes, knives, and scrapers.
Adichanallur is an important archaeological site that provides evidence of human habitation in Tamil Nadu dating back to the Paleolithic period. The site has yielded a number of important artifacts, including stone tools, pottery, and human remains. These artifacts provide valuable information about the lives of the people who lived at Adichanallur.
The other options are incorrect because they are not Paleolithic sites in Tamil Nadu. Pallavaram is a suburb of Chennai, Gudiyam Caves are located in the Coimbatore district, and Attirampakkam is a village in the Tiruvallur district.
