The correct answer would be, Alex is making dispositional (internal) attributions for his exam performance.
Explanation:
In internal dispositional attribution, the people conclude that a person's behavior is due to his internal traits and personality. The events or situations or behaviors occur due to the person's own internal factors like his abilities, feelings and traits.
For example if a person says that poor people are responsible themselves for their poverty because they are lazy, then this is a statement which shows that poor people are poor because of their laziness, which is an internal trait, while ignoring all other factors like less opportunities of education, and no equal employment opportunities for them.
Similarly as described in the given question, when Alex considers his bad grades are due to his own fault, because he is in deep depression, then he is making internal dispositional attribution.
