The effect that Emperor Ashoka had on Buddhism is that he spread Buddhism to areas outside of India. Option C is correct.
The emperor Ashoka was one of the major patrons of the Buddhist religion. He organized missions seeking to spread the concepts of Buddhism, and established many shrines related to the life of the Buddha as well. As a result of his efforts, Buddhism turnt into a worldwide religion instead of a regional one. Buddhist ideas of universal compassion, enlightenment, balance and tolerance spread as far away as Tibet, China, Greece, and Japan.
