B) Internal conflict.

Explanation: in literature, a conflict is a struggle between opposite forces, usually between a character (the main character or a very important one) and himself (internal conflict), society or another character (external conflict). In "The Tragedy of MacBeth", Act III, when guilt is causing Macbeth to imagine he sees Banquo's ghost at the banquet, he is struggling with himself (with the guilt he feels) so it is an example of an internal conflict.
