Final answer:
False. Only Macbeth sees Banquo's ghost during the banquet in Shakespeare's play 'Macbeth'; Lady Macbeth does not see the ghost and attempts to manage the situation.
Step-by-step explanation:
The statement that both Macbeth and Lady Macbeth see Banquo's ghost is false. During the banquet in Shakespeare's play 'Macbeth', it is only Macbeth who sees the ghost of Banquo. This hallucination is a manifestation of Macbeth's guilt over arranging Banquo's murder. Lady Macbeth, on the other hand, does not see the ghost and tries to calm her husband and cover up his strange behavior in front of their guests.
