Answer:
O A. frequency.
Explanation:
Intensity is how stressful the thing is while duration is how long it lasts. Stress is just what it is, and frequency is how often it repeats itself, that is, the rate at which it repeats. Every time it repeats it has its intensity and duration.

It is indeed "wrong." Why? It is because if students gossip about the teachers, the teacher would be less likely to help that student pass their class. For example, imagine if Micheal was gossiping about how the teacher walks and the teacher found out Micheal said those things. So, when Micheal needs extra credit the teacher would be less likely to give him less credit because he said those things.
Hope this helps!
