Answer:
C. believe only descendants of Muhammad may lead.
Explanation:
Option C is the one that falls under Shia in the diagram.
Shia Islam is known to be one of the two main aspects of Islam. They believe that Ali was divinely appointed to be the successor to Muhammad and to be the first Imam. The Shiites actually believe that only Allah has the right to select religious leaders; so, all the successors of Muhammad must be direct descendants of Muhammad's family. Shiites maintain that Ali, who is Muhammad's cousin and son-in-law was the right person to take over leadership after the death of Muhammad.
