The correct answer is the following: option A. The play-within-a-play in Act III of Hamlet represents Elizabethan drama by teaching a spiritual lesson to the characters of the play. Also known as "The Mousetrap", the play-within-a-play is a play that Hamlet has of visiting actors to determine whether or not his uncle, Claudius, is guilty of killing his father the King. He reenacts the events of his "real" life in which his uncle killed the previous King, just to see if he would reveal himself as the murderer. The Mousetrap serves as a teaching lesson to the characters of the play, as Hamlet reinforces his beliefs that his uncle is a murderer, and Claudius is now aware that Hamlet knows about his sins and what he did.
