Answer:
A) U.S. interference in the Muslim world.
Explanation:
Al-Qaeda is a militant Sunni islamist organization that was founded in 1988, and is considered a terrorist group by many countries and international organizations. Founded by Osama bin Laden, al-Qaeda was responsible for the September 11 attacks in the United States. This reflects the fact that al-Qaeda is greatly concerned with U. S. interference in the Muslim world. They believe that the United States is responsible for the decades-long destabilization of the region that has led to enormous strife and conflict.
