You didn't provide us with the choices of statements, but I can provide you with some general thoughts.
Key aspects of the role of religion in the civil rights movement in the United States were moral authority and organizing capabilities.
The black churches called out for a true form of Christianity, full of love for one's neighbor. They saw what many white religious persons and leaders were saying and doing as hypocritical. As an example, look at Martin Luther King, Jr.'s "Letter from a Birmingham Jail." King addressed that letter to fellow clergymen -- the white clergy of traditional Christian churches -- and used the voices of biblical prophets to show the urgency of the message of civil rights, which those religious leaders were stalling or blocking.
Malcolm X also drew a similar sort of moral authority in becoming a member of the Nation of Islam and then more generally a follower of Islam.
The black churches of America also provided an avenue for organizing the black community and facilitating the civil rights efforts they sought to carry out.
