The correct answer is d. Norway. At the beginning of the play Macbeth by William Shakespeare, Scotland is at war with Norway. In Act 1, Scene 2, the Captain reports to King Duncan that Macbeth, the play's protagonist, and Banquo, his loyal companion, have successfully defeated the invading Norwegian forces led by Macdonwald and the traitorous Thane of Cawdor. This victory sets the stage for the events that unfold throughout the play.
