Collective cohesion is to ___ as structural cohesion is to ___.

A) attraction;goals
B) unity;affect
C) belonging;membership
D) unity;stability
E) motivation;efficacy

Collective cohesion refers to the sense of unity and belonging among group members, while structural cohesion refers to the stability and interconnectedness of the group's network ties. Therefore, option D, which equates unity with both collective and structural cohesion and stability with structural cohesion, is the best choice. Options A, B, and E do not accurately capture the distinction between collective and structural cohesion. Option C equates belonging with collective cohesion but does not provide an appropriate comparison for structural cohesion.
