How did the Enlightenment influence the American and French Revolutions?

a)Ideas about full social equality caused the slave populations to rise up and overthrow their masters in favor of a democratic system.

b)Enlightenment philosophers published pamphlets in favor of monarchs’ divine right to rule, angering people into revolution.

c)Ideas about natural rights philosophy caused people to question and overthrow monarchy in favor of representative governments.

c)Enlightenment philosophy's emphasis on Protestant Christianity caused people to rebel against the authority of the Catholic Church.

I believe it's A because I read that people had ideas involving social equality and there was a revolution. Is A correct?

That is, the first C, not the second C.
