How did the muslims gain access to the iberian peninsula? a)they moved in from the western areas of europe. b)they came from northern africa. c)they attacked from northern europe. d)they revolted from the center of the peninsula.

B. They came from Northern Africa

The first push for the conquest came from a Berber force consisting of 7,000 soldiers which were loyal to the Umayyad Emir of Damascus. (They entered from the South of the peninsula, aka from Northern Africa)

Looking up the “Umayyad (Arab) Conquest of Hispania (Iberian Peninsula)” should give you more in depth information in case you’re interested.

Ithink it's b . narratives cannot be changed by other historians later
