A cultural system consists of three functional areas:

A) ecology, archeology, and ideology.
B) social structure, race, and partisanship.
C) ideology, environment, and social structure.
D) ecology, social structure, and ideology.

A cultural system is understood to encompass the relationships between ecology (the relationship of an organism with its environment), social structure (the organized pattern of social relationships and social institutions that together compose society), and ideology (the body of ideas reflecting the social needs and aspirations of an individual, group, class, or culture). These three areas work together to shape the culture of a society.
