The correct answer is D. It was a movement that questioned the authority and integrity of the Catholic Church and led to a split in the Christian religion.
Explanation:
The Reformation that occurred in the 16th century is defined as a movement or upheaval against the Catholic Church due to controversial practices such s the selling of indulgences. This implied philosophers and important figures such as Martin Luther and the general population questioning the authority of the pope and the church in general. As a result, this movement led to the emergence of alternative churches including Protestantism; also, the Catholic Church responded to the opposition by carrying out multiple reforms which were known as the Counter-Reformation.
