In the Group Counseling and Group Work core area, CACREP describes typical stages of group development (initial, transition, working, termination). The working stage (often called Stage III):

Is characterized by greater cohesion, trust, and openness,

Members assume more responsibility for the work of the group,

The leader shifts from high structure to a less directive, more facilitative role.

Because the group is more mature and self-directing in Stage III, the leader usually provides less overt intervention (Option A), while still monitoring process and safety.

Resistance (B) is often highest in earlier or transition stages; in the working stage it is present but more manageable.

Conflict resolution (C) certainly can occur, but conflict is often addressed more effectively by members themselves at this point.

Self-disclosure (D) typically increases, not decreases, in the working stage.

Thus, the most accurate distinction is A. Less leader intervention.
