C. papacy/Catholic Church

The religious institution that banned trade with certain regions controlled by Muslims was the papacy/Catholic Church (Option C).

The religious institution that banned trade with certain regions controlled by Muslims was the papacy/Catholic Church. To understand how to arrive at this answer, we can examine the historical context.

During the medieval period, the Catholic Church held significant authority and influence over Europe. In the 11th and 12th centuries, the Crusades took place, which were a series of military campaigns sanctioned by the papacy with the objective of regaining control of the Holy Land from Muslim rulers. However, after the Crusades, tensions between Christians and Muslims persisted.

To exert economic pressure on Muslim-controlled regions, the pope implemented a ban on trade with them. This was known as a papal embargo. The intention behind this embargo was to weaken the economies of these regions since trade was a vital part of their prosperity.

Therefore, the answer to your question is C. papacy/Catholic Church.
