One Especially Good Reason to Use a Form of Group

One especially good reason to use a form of group therapy in the treatment of dependent personality disorder is that:

A) because the participants are so dependent,the therapist can still control the group.
B) the group members will see how maladaptive the dependent behavior is when they observe it in the other group members.
C) the group members can model appropriate behaviors and the expression of feelings to one another.
D) the group members tend to see the role of patient as inferior when in treatment individually.
