Question

the ninety-five theses called for many reforms, including
establishing new denominations.
banning the sale of indulgences.
allowing only priests to forgive sins.
building palaces with church funds.

Explanation:

The Ninety - Five Theses, written by Martin Luther, was a key document in the Protestant Reformation. One of its main criticisms was of the sale of indulgences by the Catholic Church. Establishing new denominations was a result of the Reformation's spread, not a direct call of the theses. The theses challenged the idea that only priests could forgive sins (arguing that God's grace and individual faith played a role) and opposed misusing church funds for palace - building. So the correct option is the one about banning the sale of indulgences.

Answer:

banning the sale of indulgences.
