Which of the following belief systems became popular in Han dynasty China due to interactions with India?

While Hinduism is also an Indian belief system, it did not spread to China in the same significant manner as Buddhism during the Han dynasty. The interactions between India and China primarily favored Buddhism, which offered a more accessible framework for the Chinese populace compared to the more complex and ritualistic practices of Hinduism.

Confucianism is a native Chinese philosophy that predates the Han dynasty and was not influenced by Indian belief systems. Instead, it was the foundation of the political and social structure in China during the Han period, promoting moral integrity and proper conduct, independent of Indian interactions.

Taoism is another indigenous belief system that evolved in China independently of Indian influences. While it coexisted with Buddhism and interacted with it later, Taoism's roots lie in Chinese traditions and philosophies, making it unrelated to the cultural exchanges with India during the Han dynasty.
