Final answer:
The correct answer is Option A. Macbeth's knowledge of the future drives him to extreme action: fueled by the witches' prophecies, prompted by Banquo's suspicions, and forced to defend his kingship against the approaching English army.
Step-by-step explanation:
Macbeth's knowledge of the witches' prophecies fuels his ambition and leads to his actions to secure the throne. He becomes obsessed with the idea of becoming king and takes drastic measures, including murdering King Duncan and others, to make it happen. The witches' prophecies give him a false sense of invincibility and drive him to commit heinous acts.
Macbeth's knowledge of Banquo's suspicions prompts him to take extreme measures to eliminate a threat. He becomes paranoid and fearful that Banquo's children will inherit the throne, so he hires assassins to kill Banquo and his son Fleance.
Macbeth's knowledge of the approaching English army forces him to take drastic actions to defend his kingship. He realizes that his reign is in danger and becomes desperate to maintain control. He orders the murder of Macduff's family and becomes even more ruthless in his pursuit of power.
