The correct answer is C. Appearance versus reality.
The central theme of this play is that appearances can be deceiving. The main example of this is Macbeth, because he is seen as trustworthy by King Duncan, but everything changes after he meets the witches. He later betrays King Duncan for the throne.
One of the themes of the play "Macbeth" is appearance versus reality. What appeared to the people was very different from what was happening. When the witches said "Fair is foul, and foul is fair" they focused on the deceiving aspect of the characters in the play. Macbeth's appearance towards the people was very different from what the people thought of. King Duncan thought Macbeth to be one of his trustworthy people but he silently killed him to acquire the throne.
