Final answer:
The correct answer is option C) King Duncan came to the battlefield right after Macbeth killed Macdonwald.
Step-by-step explanation:
In the play 'Macbeth' by William Shakespeare, Macbeth is hailed as the Thane of Glamis and Cawdor by the witches, which leads him to contemplate becoming king. Right after Macbeth kills Macdonwald in the battle, King Duncan visits the battlefield to congratulate Macbeth and honor him as the new Thane of Cawdor.
Lady Macbeth and Banquo are not present on the battlefield right after Macbeth kills Macdonwald. Although the witches play a significant role in the play, they do not physically come to the battlefield at this point in the story.
