How did the Roman Catholic Church react to the loss of followers to Protestant movements?

A. It moved the Papacy to Germany.

B. It attempted to stop some of the worst abuses of the Catholic Church.

C. The Roman Catholic Church collapsed.

D. The Roman Catholic Church declared war on John Calvin.

A is the answer I believe

The best answer is B) It attempted to stop some of the worst abuses of the Catholic Church.

Although the Catholic Church did denounce Protestant movements, such as the Calvinists, as non-Christian, they also tried to implement many reforms in order to limit corruption and other factors that had created a divide between the church and the people. This mainly took place at the Council of Trent.
