The only correct answer is A) Predestination.
Theocracy is incorrect because this term refers to a government system in which a religious official (like a priest) runs a country in the name of God.
Reincarnation is incorrect because it refers to the idea of individuals being reborn after their death.
Indulgences is incorrect because this term refers to what the Catholic Church was selling to their followers. These indulgences were essentially forgiveness for their sins.
This shows that predestination can be the only correct answer.
