The important difference between bullying and harassment generally lies in the nature and context of the behavior. Bullying is often seen as a more persistent pattern of aggressive behavior that can occur in various forms (e.g., physical, verbal, social) and typically involves a power imbalance. Harassment, on the other hand, usually refers to unwanted, aggressive behavior that targets a specific characteristic, such as race, gender, or sexual orientation, and can occur less frequently but may still be quite damaging.
Given this context, the most relevant response would typically be that bullying is more persistent and can be more damaging than harassment. However, this isn't explicitly offered as an option in your list. Therefore, if we focus solely on the provided choices without further context, the best fit according to common understanding would be:
Bullying is more persistent and more damaging than harassment.
This aligns with the general understanding of how bullying and harassment are characterized.
