Answer: D. Because the Chinese religion is an ancient tradition that doesn't need to change.
During this time period, China was often reluctant to trade or to exchange information with the West. Most of the time, the reason was that the Chinese did not believe they could gain anything from this interaction. This was the case with religion as well. The Chinese government believed that the Chinese religion operated well, and that it did not need any change or improvement from missionaries. Moreover, they did not think China could benefit from adopting a different religion.
