Mark if the statement describes an event or belief that led to the crusades. a. muslims attacked the byzantine empire. b. western europe was interested in increasing trade with the byzantine empire. c. christians wanted to regain control of the holy land from the muslims.

While you did not state there is more than one correct answer, I believe there is. Four years after the Muslim had made their way into the Sea of Marmara, they raided the Byzantine coasts almost at will. So this proves the answer a) Muslims attacked the Byzantine Empire to be correct. However, it is also true that the Christians did want to spread their religion in addition to taking over certain land that they planned to use as a 'Holy Site.' So this also proves the answer c) Christians wanted to regain control of the Holy Land from the Muslims to be correct.
