Answer: B) Macbeth believes that life's ". . . a tale / Told by an idiot."
Explanation: This quote, spoken by Macbeth, means that life is brief and meaningless. In comparing life to an actor who "struts" for only an hour upon the stage and then "is heard no more," Macbeth is commenting on the fleeting nature of life. Macbeth then compares life to a story told by an "idiot," meaning that life has no more significance than an idiot's pointless rambling. Macbeth speaks these bleak words shortly after learning of his wife's death.
