The correct answer is C. "Chris earned a good grade on the test because he is really smart"
Explanation:
Fundamental attribution error (FAE), also called attribution effect occurs when people uses internal factor of the individual rather than external factors to explain a specific behavior, as the Fundamental attribution error supports the idea that the things people do are connected to who they are, in this way people attribute in an excessive way personality traits or behavior to explain actions from people, which can be mistaken as external factors are not considered. In this case, the fact that Chris got a good grade on the test is attributed to an internal factor which is Chirs intelligence. Thus, as the sentence shows an internal rather than an external factor to explain a situation experienced by an individual (Chris) this is an example of Fundamental Attribution Error.
