Obviously, the third option C.Settings are determined by the actors in the play is not a true statement about setting in dramatic plays. I bet you have never seen the actor that could decide how to organize the play or scene at all. Setting is the main point that influences on the audience making it maximally feel the play. Also setting is the place where action is occurring, so it definitely can change from one to another in order to make the play alive. Hope it is clear.
