Why is cyber bullying so difficult to stop? the bully can strike at anytimethe bully is limited to the schoolyardthe bully involves groups of people the bully is anonymous

Hi there! 

I believe that the answer is the last one, the bully is anonymous. The reason this answer is correct compared to the other answers is the fact that the first answer is kind of untrue, because it honestly depends on their schedule. The second answer isn't correct because cyberbullying is online, rather than in the schoolyard, and the third answer is incorrect because sometimes it can only include one person.

Hope I helped! (and would love brainliest :))

Asmall job market would be the answer
