The attacker who mugs you for your money most clearly illustrates

A) hindsight bias.
B) the just-world phenomenon.
C) scapegoating.
D) aggression.

The attacker who mugs someone for money is engaging in aggressive behavior, making option D the best choice. Hindsight bias (option A) refers to the tendency to believe, after an event has occurred, that one would have predicted or expected the outcome beforehand. The just-world phenomenon (option B) refers to the belief that people get what they deserve, and therefore may excuse or justify mistreatment of others based on the idea that they somehow caused their own problems. Scapegoating (option C) refers to blaming a person or group for a problem or perceived issue, often without evidence or justification. While these concepts are related to different forms of social psychology, they do not directly apply to an individual attack or mugging.
