a. Macbeth kills the current king and is rewarded by being named king himself.
Explanation:
Fair is foul and foul is fair, is a recurring theme in Macbeth, it´s first stated by three witches at the begining of the play, but it is used to say that not everything that seems god is good, and not everything that seems bad is bad, in this case when Mcbeth kills the current king and no one knows he did it, he is Kinged because they think of him as a noble Knight, not knowing that he murdered the late king and should be trialed for that.
The correct answer is A. Macbeth kills the current king and is rewarded by being named king himself.
The quote <em>"Fair is foul, and foul is fair" </em>means that things are not what they appear to be and that people may be hiding something. Macbeth killed King Duncan and then was named king - obviously, nobody knew that he is in fact the murderer, which he carefully (and successfully) tried to hide from everyone, but not for long.
