The correct answer is: B.Antagonist.

Explanation:

B.Antagonist: The antagonist is the character who creates conflict or opposes the protagonist's goals. In this case, Keith's brother is trying to thwart his efforts to earn money, which makes him the antagonist. His actions create obstacles for Keith to achieve his goal.

A.Dynamic character: A dynamic character undergoes significant change throughout the story. There’s no indication that Keith’s brother changes in a meaningful way, so he is not necessarily dynamic.
