Answer:
C. The Himalayas were not really an obstacle to movement between South Asia and China
Explanation:
The Himalayas are the largest mountain range in the world, so they are a natural barrier. The people though managed to find finds, be it through it or around it, so the people living in South Asia and China were able to communicate with each other. Most of the contact between the two regions has been through the trade routes. Some of these trade routes were going through the Himalayas, while some were through Southeast Asia, and some through sea. That the Himalayas were not stopping the contact between the two regions can be seen from several examples, such as the spread of Buddhism from India to China, lot of Chinese artifacts being found in India, people of East Asian origin living in the southern part of the Himalayas etc.
