Answer: b. when he learns that Birnam Wood is moving toward the castle.
Explanation: In Act V, of "The Tragedy of Macbeth" by William Shakespeare, Macbeth first begins to realize that he has been tricked by the prophecies when he learns that Birnam Wood is moving toward the castle. When the witches tell Macbeth that he must not fear until the Birnam Wood goes to the castle and that no man born of a woman can kill him, he feels confident. Woods don't move and all men are born from women. When Birnam Wood is approaching Dunsinane, Macbeth realizes that the predictions were misleading.
