Chad's father spends three days a week away from the home on business trips and is usually tired and grouchy on the day he returns home. This causes stress in Chad's:

A. microsystem.

B. macrosystem.

C. chronosystem.

D. exosystem.

Exo-system

Explanation:

The ecological theory was proposed by Uri Bronfenbrenner. This theory explains that the development of a person is affected by the environment as well. In this theory, we learn about why a person behaves differently in comparison to their family and compare to school, college.

In this theory, there are five stages

The micro-system The meso-system

The Exo-system: This is the system where a person does not in an active role and on the other hand actively participating in the role. We can take an example that a child who has a close relationship with their father than his mother. Father goes abroad, the child has a bad relationship with the mother. But on the other hand, this will result in a strong bond between mother and child.

The macro-system The chrono-system

So that Chad causes stress due to his exo-system.
