What was the reformation? a. a term for the changes that took place in art world b. separation between the catholic and protestant churches c. when protestant zealots smashed religious images d. none of the above

b. Separation between the Catholic and Protestant churches.

Explanation:

In the early 16th Century, there was just one church that plays the role of the religious and even the papal authority that governs the people. But with the publishing of Martin Luther's Ninety-Five Theses, there came a mass protestation about the issue of indulgences to the general public.

Indulgences are the 'passes' that a Christian believer gets,a  kind of remission from being punished for his/ her sins, through the intervention of the church. And with the increasing dissatisfaction among the people, especially the Protestants, the mass 'movement' against the Catholic church's authorities led to the Reformation, also known as the Protestant Reformation. It signals the break away from the singular Roman Catholic Church's authority.

Thus, the correct answer is option b.
