Answer:
a. the fundamental attribution error
Step-by-step explanation:
In psychology, the fundamental attribution error refers to the tendency people have to think that people acts based on personal characteristics and don't take into account the situational factors when judging other people's behavior. In other words, they think that people act in some way because of internal characteristics (such as personality) instead of thinking that it might be because of situational factors
In this example, Marilyn's professor has an strict class attendance policy and she thinks this is an indication of his over controlling personality (internal characteristic: personality) rather than a necessity because they only meet once a week for this course (situational factor). Thus, this best illustrates the fundamental attribution error.
