Answer 1

Exposition includes the introduction of the background to the main conflict; that being said I think the exposition of Macbeth is the information he obtains from the witches, and when he decides to murder Duncan. Now we have to look for a quote out of these that represents that the best. I would say B because Macbeth is figuring out that he has been named the Thane of Cawdor just like the witches told him, and after that quote he is explained why and what happened to the old Thane.
