ANSWER: excommunicaion
Explanation: Charity was not one of his abilities, because it is a process in which people give certain quantities of money to those who are in need. Because the Pope has the authority to excommunicate someone from the Church, excommunication is the correct answer. For example, during the Great Schism in 1054, he condemned the Patriarch of Constantinople. The term "heresy" is also incorrect because this was not his duty, but rather that of the Inquisition. Poverty is also not something that someone, especially the Pope, should bring, but rather a state of being without material possessions.
Hope it helps ! :) have a good day.
