Answer:
d. guilt
Explanation:
In Act III, Scene IV of "The Tragedy of Macbeth" by William Shakespeare, the emotion that we can assume Macbeth is feeling, based on his vision of Banquo's ghost is guilt. Macbeth has sent murderers to kill Banquo and Fleance. There is a banquet prepared in the castle. The murderer comes and tells Macbeth that Banquo is dead but Fleance has escaped. When Macbeth comes to sit at the table he sees Banquo's ghost sitting in his place. It is out of guilt that he is so upset at this vision.
