A Group Is in the Working Phase,and One Member States,"That

A group is in the working phase,and one member states,"That is the stupidest thing I've ever heard.I have never been in a group like this.Everyone is just whining and telling everyone else what to do when they have no clue,and people just sit there and take it.This is a waste of time." Which response by the group leader would be most therapeutic?

A) "You seem to think you know a lot already;since you know so much,perhaps you can tell us why you are back in the hospital?"
B) "I think you have made your views clear,but I wonder if others feel the same way.How does everyone else feel about the group?"
C) "It must be hard to be so angry.Perhaps the group can be of help.Mary,you were angry at first but not now;what has helped you?"
D) "I'd like to remind you that one of our group rules is that everyone is to offer only positive responses to the comments of others."
