D) Ethical conduct
Explanation:
Ethical conduct is acting in ways in which the society believes certain things should be conducted which they think are good values. According to the scientific research children learn from their surroundings and develop a thinking and behaviour which is influenced by the society.
As indicated by logical research, kids gain from their environment and creative thinking and conduct which is impacted by society. Since kids need some moral conduct as they grew up, so they would not encroach on any other person's life.
