Which set represents the ecological systems levels?

• A. Microsystem, Mesosystem, Exosystem, Macrosystem.
• B. Local community, neighborhood, city governance, cultural norms.
• C. Genetic, developmental, neural, cognitive.
• D. Individual, family, school, work.

Answer: (D)

Bronfenbrenner's ecological systems theory describes nested environmental levels that shape development. The closest environment to the individual is the microsystem, including immediate relationships and settings like family, classmates, and teachers. The next layer, the mesosystem, consists of the links and interactions between those microsystems—such as how family routines affect school life or how parent-teacher communications influence a child. Surrounding that is the exosystem, which comprises settings that indirectly affect the person, like a parent's workplace or community resources. The broadest layer, the macrosystem, encompasses cultural values, laws, and societal norms that shape all the inner layers. Some models also add the chronosystem to account for time and life transitions.

This set of four named levels—Microsystem, Mesosystem, Exosystem, Macrosystem—best represents the ecological systems framework. The other options mix contexts or domains that aren’t the formal layered structure: an assortment of contexts without the specific levels, or domains like genetic or cognitive factors, which are not environmental levels in this theory.
