Well they all are very dangerous at certain levels as if you get angry you can become violent or depressed while being happy you can be over happy and be crazy and do things that you shouldnt do eg. take drugs but with fustration it can be very dangerous because people can suddenly lash out without any prewarning like with anger but i do think that a. anger is very dangerous because of the consequences that could happen due to the anger.
Its probably A because i think they would have said physical therapists if B was the answer since there talking about getting fit.
0.5 to 2 pounds per week.
Hope this helps!
