There isn't a specific reading. How are we supposed to know the story you're doing? Maybe if you inform me of the lines I can help
When they have heard the Banquo had died, Macbeth was angered because the murderers were not able to kill Fleance. The King saw the ghost of Banquo sitting on his throne. Macbeth was very surprised and tried to talk to the ghost which he was the only person who could see. Lady Macbeth tried to save her husband's face by saying telling the ghost to disregard Macbeth's behavior. She scolded him and told him to act normally.
I believe it is B - It provides momentum throughout the poem.
(please let me know if I am wrong, also I apologize in advanced just in case it is wrong.)
