If morality comes from a deity's commands, then one of two things must be true. what are the two things? [select two.]

Seems like the question is missing options here, I will explain the simple answer below. The answer is:
1) The deity commands things that are already moral, 

2) The deity could have commanded anything and that thing would have been moral.

The choice offers a dilemma that why a deity had commanded something which already was moral, if not then why the deity did not command that thing to be moral.
