Afollower of muhammad and islam.
a. christian. b. cultural diffusion. c. muslim. d. daimyo

Muslim. 

Muhammad and Islam are two things that are in the Koran. 

Using process of elimination we can get rid of answer d. as they are japanese lords. we can eleminate a. because Christians instead follow Jesus "Christ" and of the christian religion. cultural diffusion isn't a religion or stature but rather a movement of an idea so we can eliminate that. what we're left with is Muslim. c is your answer
