please someone help

Correct answers are:

b. they targeted the spread of Islam

d. they were concerned with lands and sacred sites in the "Holy Lands” being occupied by Muslims

Explanation:

Option A is not correct as they lasted less than 200 years, from 1096 to 1271.

Option C is not correct as there were eight Crusades (the number that have been mentioned in textbooks).

Option B is correct as Crusades tried to prevent the spreading of Islam, especially in the period when Turks Seljuks started spreading their power.

Option D is also correct because they wanted to deliberate Holy Land from the hands of Muslims, as they were usually saying.
