Answer:
Structural functionalism
Step-by-step explanation:
In sociology, structural-functionalist theory explains the functioning of a society from social actions. That is, how the various actions of individuals make society function more or less stably. From actions arise social roles, from which in turn arise social institutions. Influenced by Durkheim and Radcliffe-Brown, structural-functionalist sociological theory took shape with Talcott Parsons (1902–1979) and Robert K. Merton (1910–2003) in the postwar United States.
