Interdependence is a key quality of groups and it requires that

A) all members of the group influence each other equally.
B) members' outcomes depend,in part,on the actions of others in the group.
C) influence is reciprocal,in the sense that if A influences B,then B influences A.
D) group members share a common goal.

Interdependence means that the outcomes of group members are not solely dependent on their own actions, but also on the actions of others in the group. This means that members' outcomes depend, in part, on the actions of others in the group. While choice D (group members sharing a common goal) is often a characteristic of interdependent groups, it is not the defining quality of interdependence. Choices A and C are incorrect because they do not capture the essence of interdependence, which is the mutual reliance on others in achieving goals or outcomes.
