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

While Hinduism is a major belief system in India, it did not spread to China in the same manner or with the same impact as Buddhism during the Han dynasty. Hindu practices and beliefs were not as influential in the cultural exchanges of this period, making it less prevalent in Chinese society compared to Buddhism.

Confucianism, founded by Confucius, was already well established in China long before the Han dynasty. It is a native belief system that focuses on ethics, social harmony, and governance, rather than being imported from India. Its popularity in Han China was due to its own historical significance, not due to interactions with India.

Taoism is another indigenous Chinese philosophy that emphasizes living in harmony with the Tao, or the Way. Like Confucianism, it was already a part of Chinese culture prior to the Han dynasty and was not influenced by Indian belief systems. Its growth during this period was independent of Indian interactions.
