According to functionalist theory, which of the following best explains the existence of social inequality?

Functionalist theory suggests that social inequality exists because it serves a purpose in society. This theory argues that different roles and jobs are needed for society to function smoothly. For example, if everyone had the same skills and jobs, there would be no one to do the more difficult and specialized tasks, like doctors or engineers. Therefore, inequality can help motivate people to work hard and achieve higher positions, which keeps society running efficiently. In this way, functionalists believe that social inequality is not just a problem, but a necessary part of how society operates.
