Answer: Fundamental attribution error
Step-by-step explanation: Fundamental attribution error is described as behavior used for judging other individuals on the basis of personal factors rather than evaluating on external situational components. Internal factor that is taken into account for judging others is usually their inner personality .
According to the mentioned case in question,Marilyn is judging her professor on basis of fundamental attribution error.She is not considering the good fact that strict attendance policy is required for completing the course on time because limited sessions in a week are provided to him.
Thus, the professor is behaving strict so that every student is present in class to understand the session.Marilyn is rather thinking that he has a strict personality due to personal factor.
