All Of The Answers are correct. Coping skills can help a person mentally and physically and calm them down, Management and Employee Involvement can prevent someone from being violent because they can call the cops if something happens, and warning signs can benefit you because it gives you time to get out of the situation or get the individual help. but if that is not the correct answer, Coping Skills would be the 2nd choice, because itś the most effective way, in my opinion!
