A social worker is conducting an insight oriented psychotherapy group. Although all parties have been briefed on confidentiality, during the group session, one individual admits discussing the group with friends and family. The BEST way for the social worker to handle this situation is to:
A. encourage group members to confront the individual regarding this breach
B. see the client outside of the group setting to explain the inappropriateness of this behavior
C. have other group members vote on whether this client can stay in the group
D. have group members discuss this situation and reach a mutually satisfactory resolution
