Why Does Macbeth Seek Out the Sisters in Act 4 Scene 1?
Macbeth revisits the witches in Act 4, Scene 1 of Shakespeare's Macbeth not for any of the mentioned incorrect options (such as seeking a refund, inquiring about Lady Macbeth's fate, or to reproach the witches for his predicament). Instead, he seeks their knowledge and advice to understand more about his destiny and to secure his position as king.

After these events transpired, Macbeth's sense of security was troubled by anxiety and paranoia, prompting him to seek further insight into his future. Thus, the answer is D. He wants advice about what to do next.
