The best and most correct answer among the choices provided by the question is the third choice or letter C which is "actively promoted legalism as a way to keep control of the people."  Legalism  in Christian theology, is the act of putting law [clarification needed]above gospel by establishing requirements for salvation beyond repentance and faith in Jesus Christ and reducing the broad, inclusive and general precepts of the Bible to narrow and rigid moral codes.
