Answer:
Buddhism
Step-by-step explanation:
Confucianism originated in China in roughly 479 BCE. Confucianism was founded by a philosopher named Confucius. Some people believe that Confucianism isn't even a religion, since there aren't any gods. Many people say it is better described as a philosophy.
Therefore, the answer can't be Confucianism, because it isn't a religion and it did not originate in India in 500 BCE.
The answer must be Buddhism. Buddhism is a religion founded by the Buddha: Siddhartha Gautama. It originated in India in about the fifth or sixth century BCE. It has millions of followers around the globe today.
