Answer:
C. the microsystem
Explanation:
Uriel Bronfenbrenner postulated five levels of external influence on a child's development, these are the microsystem, the mesosystem, the exosystem, the macrosystem and the chronosystem.
The exosystem is concerned with the linkages that exist between two or more systems, they are social systems that affects the child indirectly. These institutions may not include the developing child but affect them, example of this is a community school, parents work place, mass media.
While the school the child attends is an example of a microsystem, a school in the community which the child does not attend but is in the community may have indirect effect on the child and as such is classified as an exosystem.
