Answer:
The correct answer is Constantinople was a Christian city from which the Crusaders marched on Jerusalem.

the First Crusade was the first of many attempts to recapture Jerusalem, the Holy City, and it took place between 1096 and 1099. It was called by the Pope Urban II in 1095. By this time, Constantinople had already converted to Christianity in 312 AD when Constantine decided to adopt this religion. Due to this, letter D is the correct answer.
