The best definition of bioecological theory is

A) Every child is at the center of concentric circles of contexts
B) Every child should be the star in the home
C) Every child should be responsible for his environment
D) Every child should have specific duties at home

Bioecological theory, developed by Urie Bronfenbrenner, suggests that every child is at the center of concentric circles of contexts, including microsystems (immediate surroundings), mesosystems (interactions between microsystems), exosystems (indirect environments), macrosystems (cultural values and beliefs), and chronosystems (historical context and changes over time). This theory emphasizes the complex and interconnected nature of a child's environment and how it can shape their development.
