AThe third apparition is a crowned child holding a tree, which signifies that Macbeth will never be defeated until Birnam Wood comes to Dunsinane Hill. This prophecy gives Macbeth a false sense of security, as he believes such an event is impossible, leading him to underestimate the threat posed by Malcolm's forces.
BThe third apparition is a bloody child, which signifies that no man born of a woman will harm Macbeth. This prophecy emboldens Macbeth, making him overconfident and dismissive of potential threats, as he interprets it to mean he is invincible.
CThe third apparition is an armed head, which warns Macbeth to beware Macduff. This prophecy directly influences Macbeth to order the murder of Macduff's family, although he ultimately fails to eliminate Macduff himself
DThe third apparition is a line of eight kings, with the last king holding a mirror. This apparition signifies the continuation of Banquo's lineage, unsettling Macbeth as it reaffirms the witches' initial prophecy that Banquo's descendants will inherit the throne
