How does Lady Macbeth influence Macbeth's decision to murder Duncan? A. She laughs at Macbeth's belief in the witches' prophecy, making him angry enough to kill the king. B. She warns Macbeth that if he does not kill the king, his children will go hungry and likely die. C. She tells Macbeth how proud she is of him, calling him strong and manly, until he agrees to kill the king. D. She calls Macbeth weak and questions his strength of character, pushing him to agree to the crime.

I believe that the answer is D. In Act 1, Scene 7, Lines 39-49, Lady Macbeth asks why Macbeth has decided to cancel the assassination. She questions his strength of character by telling him he will "live a coward in thine own esteem," meaning that if he does not do it, he will be a coward. Later on, in the same act and scene, lines 56-58, she begins to doubt his manhood, stating that he will be less of a man if he were to back out now and not kill Duncan. This is why I believe the answer to your question is D.
