The correct option is "C. During the Han dynasty, the teachings in the Analects of Confucius set the tone for public life."
The Analects of Confucius are the written version of a series of talks that Confucius gave to his disciples as well as the discussions they held among them. The original title in Chinese, Lun Yǔ, means "discussions about the words". For more than two thousand years, the Analects have been part of the studies of Chinese schools since it was considered that no man could reach a good moral level and intelligence without knowing the work of Confucius.
