Final answer:
Functionalist perspectives are based on the assumption that society is a stable, orderly system composed of interrelated parts, each of which (ideally) contributes to the overall stability of the society. (Option A)
Step-by-step explanation:
Functionalist perspectives, denoted by option A, revolve around the idea that society functions as a stable and orderly system, akin to a well-oiled machine. This theoretical framework, primarily associated with sociologists like Emile Durkheim and Talcott Parsons, posits that various social institutions, such as family, education, religion, and government, work in harmony to maintain social equilibrium. Each institution has a specific function that contributes to the overall stability and functioning of society.
In functionalism, these institutions are believed to serve essential roles in meeting society's needs, such as socialization, the regulation of behavior, and the allocation of resources. When all parts of society fulfill their functions adequately, the result is social cohesion and stability. Deviance or dysfunction within any of these parts is seen as an anomaly that requires correction to restore balance.
Therefore, the correct option is: A. Functionalist perspectives
