Answer:
d. Social loafing
Step-by-step explanation:
In psychology, the term social loafing refers to the phenomenon by which a person exerts less effort to achieve a goal when he or she works in a group than when he or she is working alone. Social loafing lowers the level of satisfaction among the members of the group since they become frustrated with the person that is exerting less effort than the rest of them.
In this example, Raj and his cousins are asked to help their uncle move to a new house. Raj ate most of the snacks and had all the soda and did not move as many boxes as there rest of the group. We can see that Raj is exerting less effort than the rest of the cousins and is not being really helpful. Therefore, Raj's behavior is an example of social loafing.
