Answer:
b. fundamental attribution error
Step-by-step explanation:
In psychology, the fundamental attribution error refers to the tendency that we have to explain someone else's behavior based on internal factors (like their personality) and underestimating the influence of external factors on their behavior.
On the other way, we do the opposite when it comes to our own behavior, we tend to overemphasize the influence of situational factors when explaining our behavior and we underestimate the role our personality plays.
Therefore, the tendency to overemphasize the importance of personality factors when explaining someone else's behaviors while overemphasizing situational factors when explaining your own behaviors, is called the fundamental attribution error.
