The scenario that best illustrates social loafing is when one individual takes on the workload while others relax. Social loafing refers to the phenomenon where individuals exert less effort when working in a group compared to when they are working alone. This can occur because individuals may feel less accountable in a group setting or believe that their efforts will not significantly impact the overall outcome, leading to reduced motivation to contribute.

In this scenario, the presence of one person taking on the majority of the work highlights the lack of participation and effort from the other group members, which is a clear manifestation of social loafing. It shows how the dynamics of teamwork can lead to uneven distributions of workload, with some members opting to benefit from the efforts of others without contributing equally. This phenomenon can significantly affect group performance and outcomes, making it an important concept in understanding group behavior and dynamics in social psychology.
