The correct answer is: All of the above.

Ancient literary sources like the Mahabharata and Puranas mention regions in the present-day Arunachal Pradesh, referring to them as:

  • Kiratadesa. The Mahabharata mentions the Kirata people, who lived in the eastern Himalayas. The Puranas also mention the Kirata people, and say that they were ruled by a king named Narakasura.
  • Pragjyotisha. The Mahabharata mentions the kingdom of Pragjyotisha, which was located in the eastern Himalayas. The Puranas also mention Pragjyotisha, and say that it was ruled by a king named Bhagadatta.
  • Kamarupa. The Puranas mention the kingdom of Kamarupa, which was located in the eastern Himalayas. The Puranas say that Kamarupa was ruled by a king named Narakasura.

The Mahabharata and Puranas are ancient Indian texts that contain a wealth of information about the history and culture of India. These texts are often cited as evidence of the existence of ancient kingdoms and empires in India. The mention of regions in the present-day Arunachal Pradesh in these texts suggests that these regions were inhabited by people who were part of Indian civilization for centuries.
