Answer:
Correct answer is B. Galileo affirmed the Earth was not the center of the universe.
Explanation:
Only option B is correct because his teachings totally opposed the ideas of church. Church stressed out that Earth is the center of universe, and that everything revolves around Earth.
His discoveries undermined the authority of the Church, which was unacceptable at the time.
All other options were not the reasons why Church opposed Galileo.
