A. This group believes only descendants of Muhammad should be caliph
B. The majority of Muslims are this group
C. This group views the Quran as the holy book of Islam.
A is correct, because Shia(10-20% according to shafaqna.com) is one of the two main branches of Muslim religion, and the other one being Sunni, believing in using a council of people to elect their leader. Those two do not get along.
