A three-year-old boy observes his father yelling at his mother every time she says something the father doesn't like. Based on principles of observational learning, in the future whenever the mother says something to the boy that he does not like, the boy is MOST likely to do which of the following?

A) yell at his mother
B) yell at his sister
C) go and tell his father what the mother said
D) yell at his father

The three-year-old boy is observing his father yell at his mother whenever he disagrees with her. This is an example of observational learning. The boy is likely to imitate his father's behavior and yell at his mother when he disagrees with her. This behavior is reinforced by the fact that his father is doing it as well. Option B and C are not relevant as they do not relate to the observed behavior. Option D is not likely as the boy is not directly experiencing negative consequences from his father's behavior towards his mother.
