Answer:
E) social loafing
Step-by-step explanation:
In sociology, social loafing takes place when the members of a team or group do not assume their share of responsibility and work because they believe that someone else in the team will do the work for them. Since each individual contribution is not defined, then individuals will use that excuse to simply not work hard enough or not work at all.
E.g. it is the same that happens in school when an assignment is given to a large number of students, e.g. 5-6, and only 1 or 2 of them actually do all the work.
