In Today's Society, Children's Exposure to Psychological Trauma Is, Unfortunately

In today's society, children's exposure to psychological trauma is, unfortunately, a common occurrence. Do all children subjected to something terrible (like losing a family member due to a shooting or act of terrorism) need psychotherapy, and why?

A) Yes, because they need professional help coping with the initial shock, rage, and other all-consuming emotions.
B) Yes, the traumatic event will affect them for life.
C) Not necessarily, since initial distress is to be expected and therefore is not cause for concern.
D) Not necessarily, but the child's adjustment does need to be closely monitored, because the possibility of long-term major coping difficulties cannot be ruled out.
