Correct answer: (A) Task-oriented roles that help the group achieve its goal.; (B) Socio-emotional roles involving support and nurturance of members.; (C) Prescriptive norms specifying what members should do.
Explanation
Roles specify expected contributions: task and socio-emotional roles are both structural features. Norms prescribe acceptable conduct, so C also belongs. Monitoring is an activity or control process rather than a structural role/norm category as phrased. Thus select A,B,C.
