Final Answer:
The play "Macbeth," who encourages Macbeth to kill King Duncan is A. Lady Macbeth
Step-by-step explanation:
In the play "Macbeth," Lady Macbeth is the one who encourages her husband, Macbeth, to kill King Duncan. Lady Macbeth is a powerful and manipulative character who wants to see her husband ascend to the throne. She believes that Macbeth has the ability to become king but needs to overcome his moral scruples to achieve his goal.
Upon receiving a prophecy from the three witches that Macbeth will become the king, Lady Macbeth writes a letter to her husband, urging him to act on the prophecy. She accuses Macbeth of being a coward and questions his manhood, saying that he is not fit to be a king if he cannot take action to claim the throne. Lady Macbeth's persuasive speech and manipulation ultimately convince Macbeth to commit the murder of King Duncan.
Throughout the play, Lady Macbeth continues to play an active role in encouraging and supporting Macbeth's actions, even as he becomes increasingly consumed by guilt and paranoia. Her influence can be seen as a key factor in Macbeth's descent into madness and tyranny.
Correct option is A. Lady Macbeth
