Which was a reason for the First Crusade?

Answer 1

The answer is C. When the Seljuk Turks took control of the Holy Land, it became more dangerous for Christians to travel there.

"c. When the Seljuk Turks took control of the Holy Land, it became more dangerous for Christians to travel there" would be the best option, since most of the Crusades were largely about "taking back the Holy Land".
