Which of the following team-based interventions can effectively reduce the effects of social loafing?

Within the HRPA Professional Competency Framework (Organizational Effectiveness), HR is expected to design team structures and practices that clarify roles, responsibilities, and performance expectations to improve collaboration and outcomes. Establishing clear individual accountability—explicit goals, role clarity, and measurable individual contributions within team objectives—reduces social loafing by making effort and results visible and attributable. Increasing team size (A) typically exacerbates diffusion of responsibility; anonymous peer evaluations (B) provide limited preventive effect; general team-building (D) can support cohesion but does not by itself ensure accountable contribution.
