What evidence from the text leads you to believe that the dagger Macbeth sees is an illusion?
 A."Is this a dagger which I see before me, / The handle toward my hand?" B."Thou marshall'st me the way that I was going; / And such an instrument I was to use." C."Or art thou but / A dagger of the mind" D."I see thee yet, in form as palpable / As this which now I draw."
