Final answer:
The event that illustrates the haunting and torment experienced by Macbeth and Lady Macbeth in 'Macbeth' is Lady Macbeth's death.
Step-by-step explanation:
The event that illustrates the haunting and torment experienced by Macbeth and Lady Macbeth in 'Macbeth' is Lady Macbeth's death (option B).
Lady Macbeth is shown to be tormented by guilt and remorse for her role in the murder of King Duncan. This is evident in her sleepwalking scene, where she repeatedly tries to wash the imaginary blood from her hands, symbolizing her psychological torment.
Macbeth's torment is depicted through his hallucinations and paranoia. He is haunted by Banquo's ghost, whom he ordered to be murdered. In Act 3, Macbeth sees the ghost of Banquo sitting at a banquet, which is a manifestation of his guilt.
