What does the microsystem comprise in family systems theory?

• A. Government policies and cultural norms
• B. Global economic conditions
• C. Genetic information only
• D. The nuclear family, extended family members, and their roles and expectations

Answer: (D)

The microsystem is the immediate, day-to-day environment in which a person directly interacts and forms relationships. In family systems theory, this means the family network itself—the nuclear family and extended relatives—and the roles each member plays within that network, along with the expectations attached to those roles. The way family members communicate, parent and sibling interactions, caregiving routines, support, and conflicts all shape development in real time.

That’s why this option fits best: it centers on the direct, intimate social circle—the family—along with who is involved and what is expected of them. The other choices point to broader layers of influence or biology rather than the direct, everyday social environment: government policies and cultural norms belong to the macrosystem; global economic conditions also relate to larger systemic factors; genetic information pertains to biology rather than social interactions.
