Hey!

![\Large\boxed{\mathsf{Option~D!}}](https://img.qammunity.org/2020/formulas/english/middle-school/luixhrh2gp677pgvn03snbvilanwhye8g3.png)
In the short story it doesn't state the point of the fight. When we get to the film it states that the fight started because character B attacks character A with no reason. Option A, B, and C are incorrect because character B isn't humorous, likable, or sad. When it states "Character B attacks him without a reason," this means that this character is heartless and doesn't care for other people's feelings other then his/her own.
