What evidence from the text supports the idea that lady Macbeth questions her husbands resolve to kill the king?
A.Glamis thou art, and Cawdor; and shalt be / What this art promised.
B. What they wouldst highly, / that wouldst thou holily; wouldst not play false,/ and yet wouldst wrongly win.
C. Hie thee hither, / That I may pour my spirits in thine ear.
D. Which date and metaphysical aid doth seem / To have the crowned withal.

William Shakespeare's Macbeth revolves around the story of how Macbeth became infatuated with power that led to his murderous deeds. His greed, supported by his wife, would also eventually become the source of their downfall.

In Act I scene v, we find Lady Macbeth reading a letter seemingly from her husband Macbeth, informing her about the prophecy of the three witches. After she is done reading the letter, she admits that she knows what he wants. But then, she doesn't think that he has what it takes to get what he deserves, for it requires the skill to be ruthless and evil. And he, as a person, doesn't seem likely to be able to achieve that. He may be willing to get the power and authority whatever way possible, but with a heart of "human kindness" that is in him, he doesn't have the resolve to do that. When she says "What they wouldst highly, / that wouldst thou holily; wouldst not play false,/ and yet wouldst wrongly win" she meant that he wants to get what he wants in a good manner, but what he wants needs to be achieved by unfair means, for what he wants isn't his and needs to be taken by force and evil deeds.
