Final answer:
Group dependent contingencies may lead to stigmatization of one group member is True option (A).
Step-by-step explanation:
The statement that group dependent contingencies may lead to stigmatization of one group member is True option (A).
Stigmatization refers to the process of labeling and discriminating against individuals or groups based on certain characteristics or attributes. In the context of group dependent contingencies, when one group member deviates from the norms or expectations of the group, they may be stigmatized by other group members.
For example, if a student in a study group consistently underperforms or fails to contribute, they may be stigmatized as being lazy or unhelpful by other group members.
