Why is it necessary to clarify roles while working in a group?

Correct answer: To understand responsibilities

Clarifying roles means deciding who will do which part of a shared task. It gives every group member a clear sense of duty and prevents two people from doing the same work while another task is ignored. Role clarity also supports cooperation, accountability, and timely completion. It does not mean controlling or confusing people; it helps everyone contribute according to the plan.

The question asks why roles must be clarified in group work. The suitable reason is that members need to understand their responsibilities, so option B is correct. When duties are known, members can coordinate, report progress, and seek help at the right time. The other choices describe harmful purposes and cannot support effective teamwork.
