The correct answer is - Adherents.
The adherents, from a religious perspective, are the people that are followers or members of a particular religion. These people have committed themselves to a certain set of religious ides, practices, to live their life in a manner that the religion suggests or imposes, and believe in the god or gods of that religion.
There's multiple religions, and all of them have different philosophies and practices. That leads to different types of adherents, who practice different things, show their commitment to a different god or gods, and act differently in the society.
