Answer:
Social loafing would be best demonstrated by members of:
C. Group 3 arriving at a consensus in the shortest amount of time compared to Groups 2 and 4.
Step-by-step explanation:
In social psychology, the term social loafing refers to our tendency to work less or to make less effort when we are working with a group instead of alone. When in groups, we tend to worry less about doing our best, which explains why, sometimes, groups are less effective than individuals.
An example of that would be, as mentioned in option C, a group that arrives at a consensus in the shortest amount of time when compared to two other groups. That fact may be indicative of social loafing. It is likely that the members simply did not feel like discussing and chose to go with the first idea or opinion presented.
