Answer:
correspondence bias
Step-by-step explanation:
Fundamental attribution error or correspondence bias is a phenomena where a person believes an action to be related to the personality of another person and ignores the role the situation might have played in that action. It believes that people's actions reflect who they are without considering the role of the situation or environment.
Here, Irv was suffering from flu and not well which described his situation. But the teacher still ignored these factors and blamed Irv's poor performance in test on his personality and behaviour. He assumed that Irv did not study on purpose and was a lazy student which in fact was not true hence he teacher is displaying fundamental attribution error or correspondence bias.
