Final answer:
The correct answer is option 1) Microsystem.
Step-by-step explanation:
The layer that involves the activities and interaction patterns in the child's immediate surroundings, such as school, family, day care, little league team, and similar environments, is referred to as the Microsystem. This concept is a part of Bronfenbrenner's ecological systems theory, which outlines various levels of influence on an individual's development.
The Microsystem is the innermost layer and describes direct interactions that influence the individual on a personal and immediate level. Sociology often examines the interconnections of individuals at different scales, and the Microsystem correlates to that micro-level study focusing on small groups and individual interactions.
