The correct answer is D.
After hearing the witches prophecy, Macbeth, along with the help of his wife, kills Duncan and becomes King himself.
However, preoccupied about the second part of the prophecy, which said that Banquo's offspring would begin a line of Scottish kings, he orders the murders of Banquo and his son, Fleance.
Later, frightened after seeing Banquo's ghost, Macbeth goes visit the witches again, who show him a sequence of demons and spirits and warn him about Macduff.
Finally, when fighting against Macduff, Macbeth learns that he was not "born of woman" but “untimely ripped” from his mother’s womb and, therefore, can kill him.
