Final answer:
In 'Macbeth', Macduff is the Thane of Fife who discovers King Duncan's body and ultimately kills Macbeth.
Step-by-step explanation:
In Shakespeare's Macbeth, the character who is the Thane of Fife, is commanded by Duncan to visit him early in the morning at Macbeth's castle, discovers King Duncan's body, and eventually kills Macbeth is C) Macduff. Neither Banquo, Macbeth, nor Duncan fulfill all the roles mentioned in the question. Banquo is a general in the King's army and Macbeth's friend who does not discover Duncan's body nor does he kill Macbeth. Macbeth is the main protagonist who becomes the Thane of Cawdor and later, King, after Duncan's murder, which he commits himself. Lastly, Duncan is the King of Scotland whose murder catalyzes the events of the play. Macduff, however, is the one who finds Duncan dead and ultimately brings about Macbeth's downfall. In Shakespeare's "Macbeth," the Thane of Fife is Macduff. Initially commanded by Duncan to visit Macbeth's castle early in the morning, Macduff discovers the lifeless body of King Duncan, marking the tragic beginning of Macbeth's descent into tyranny. Macduff becomes a pivotal character in the play, embodying the prophetic warnings given to Macbeth by the witches. Later in the narrative, Macduff emerges as a symbol of justice and retribution. His determination to avenge Duncan's murder and his ultimate confrontation with Macbeth in the final act contribute significantly to the play's exploration of ambition, power, and the consequences of unchecked tyranny.
