Explain the function of group roles.

Group roles serve the essential function of providing structure for individual responsibilities within a team. Each role defines specific tasks or responsibilities assigned to different members, ensuring that everyone knows what is expected of them and how they contribute to the group’s overall objectives. By clearly delineating these roles, the group can operate more efficiently, as members can focus on their assigned tasks while also leveraging the strengths of their peers. This structured approach promotes accountability and helps avoid overlaps or gaps in responsibilities, contributing to the group's effectiveness in achieving its goals.

In contrast, the other options do not align with the purpose of group roles. Creating confusion among group members would hinder productivity and communication. Eliminating collaboration would undermine the very essence of teamwork, which relies on cooperation and shared input. Lastly, ensuring that all members do the same tasks would disregard the diverse skills and abilities of individuals, leading to inefficiency and frustration. Thus, the correct answer reflects the importance of clear role delineation in fostering a productive and well-organized group dynamic.
