Which of the following best exemplifies physical punishment (spanking) ?

A) It is legal in child care programs
B) It is likely to make the child fearful or angry, or cause resentment

D) It is likely to enhance the "teachable moment"

Spanking is a form of physical punishment which is likely to make the child fearful or angry, or cause resentment. It is not the best approach to changing undesirable behavior, as there are more effective and positive ways to discipline a child. Additionally, physical punishment can have negative long-term effects on a child's mental health and behavior.
