Consider two scenarios:

Scenario A: Two classmates of equal physical size and social standing have a heated argument over a group project, calling each other names. This happens on two separate occasions.

Scenario B: A physically imposing, popular senior repeatedly takes lunch money from a smaller, socially isolated freshman, threatening them if they tell anyone.

Which statement best analyzes the fundamental difference that classifies Scenario B as bullying, while Scenario A is best described as a conflict?
