The correct answer is: b) Malinithan.
Malinithan is an archaeological site in Arunachal Pradesh, India. It is located in the Changlang district, near the town of Miao. The site is known for its Paleolithic tools, which have been dated to around 200,000 years old. The tools are made of stone and include hand axes, cleavers, and scrapers. They are similar to tools found in other Paleolithic sites in India and Southeast Asia.
The discovery of the tools at Malinithan suggests that humans were living in Arunachal Pradesh at least 200,000 years ago. This makes it one of the earliest known human settlements in India. The tools also provide evidence of the early development of human technology.
