Answer:
The correct option is C) encourage the member to discuss the decision with the group
Explanation:
When a member wants to leave a group, the counsellor should tell him that as he/she is the member of a team so he should discuss the matter with the team members. Informed consent is necessary. The members of a team know how the situation can be made better and they might even know ways to persuade the member to stay if they want him to stay.
The decision in a group should always be taken by the mutual consent of the group members and not just by a single person.
