All of these are examples of dramatic irony except a) a character kills himself out of grief for the death of his sweetheart because (unlike the audience) he does not realize his love is still alive. b) a character in a horror film climbs the stairs and opens the door to a room the audience recently saw the killer enter, a fact unknown to the character in the movie. c) the audience is privy to a character's inner thoughts which stand in contrast to his words and actions while other characters are on stage. d) a character's lines are filled with sarcasm and hyperbole.
