Answer:
C. "Or art thou but/ A dagger of the mind."
Explanation:
Illusion exemplifies a deceptive or misleading idea or belief. It represents a false mental interpretation that is believed to be true. Shakespeare's famous tragedy "Macbeth" displays a central theme of Reality vs Illusion. Macbeth after killing Duncan is terrified by intense guilt. He frequently hears hallucinating(illusion) voices that he believes to be the reality. He fears that he is cursed to never sleep again or pronounce the holy word "Amen". He is so deeply guilt-stricken that he brings the bloody daggers with him. He sees the blood of his hands to be plunged into ocean and turn the entire ocean red. This exaggeration reflects the intensity of his guilt that he begins to hallucinate. Thus, option C reflects the illusions faced by Macbeth due to his untamed ambition that leads him to his tragic end.
