Does Morality Depend on God for Its Legitimacy? Specifically, Is

Does morality depend on God for its legitimacy? Specifically, is an action right (or wrong) because God commands that it be so-or is it right (or wrong) independent of God's commands, so that God must in fact answer to the moral law? The view that morality does depend on God is known as the "divine command theory," and Rachels critiques it in this reading. He argues that this conception of morality is false and that neither the theist nor the nontheist should accept it.
-According to Rachels, if right conduct is right because God commands it, then

A) morality is independent of God.
B) God's commands are arbitrary.
C) morality existed before God existed.
D) God is not all-powerful.
