Thanks for pointing this out. As written answer choice D should be accepted as it is not equal to sin(120) either.

We've updated the question to made answer choice D equal, so that answer choice C is the only one that is not equal. I've manually updated your grade on the quiz to accept your answer as it should have been accepted as well.
