The correct answer is B.
Appearance vs Reality is one of the main themes in Macbeth.
Macbeth is presented as an honorable man who everyone respects. However, deep inside, he is an evil person who would do anything to get the power he desires.
At the same time, Lady Macbeth, is shown as a righteous woman, but in reality, it is her who plans the assassination of King Duncan to help her husband to become King.
