Answer:
The correct answer is C) Macbeth has "black and deep desires" regarding Duncan's son and heir, Malcom.
Step-by-step explanation:
In the story of Macbeth, the three witches when they meet Macbeth the first time addressed him by his current title Thane of Glamis among other things, they reveal to him that the Kingship of Scotland would be his in the future.
Fast forward to Act I scene IV, Thane of Cawdor previously addressed as Macbeth now has reasons to believe the predictions of the witches with respect to his ascension to the Scottish throne.
So when King Duncan reveals that his son Malcom will succeed him as King, Macbeth becomes vexed. He soliloquises as follows:
"The Prince of Cumberland! That is a step
On which I must fall down or else o’erleap
For in my way it lies. Stars, hide your fires;
Let no light see my black and deep desires."
Based on his knowledge of the current events and the prophesy, the throne of Scotland was not his to give up or take by force by eliminating or stepping over Malcom.
Cheers!
