Answer:
C. At the start of the play, he is loyal to Duncan, but he later kills Duncan to get what he wants
Explanation:
In the begining of the famous Shakespeare's play, we are introduced to Macbeth, who is a King Duncan's general.
After having successfully defeated the enemy army, on the way home Macbeth is encountered by three witches, who tell him the prophecy that he will be named a thane (rank of nobility in Scotland) and later a king.
Sceptical at first, after really being named a thane, Macbeth starts believing in the prophecy.
Tortured by ambition and persuaded by his greedy wife, Macbeth kills King Duncan, whose sons leave the country which enables him to become new King of Scotland.
Torn between guilt and desire to remain king, Macbeth is driven to madness and paranoia, killing anyone who pose a potential threat to his throne.
