Research on the social psychological underpinnings of prejudice might be said to have its roots in research by

Robert Baron (1976) conducted a field experiment to study drivers' responses to a car that hesitated when a stoplight turned green. He found that when a confederate hobbled across the street on crutches in front of the lead car in the intersection, fewer drivers behind the lead car honked their horns. According to Baron, why was that?

A) Drivers at the rear were distracted by the sight of a person on crutches. B) Drivers at the rear were afraid honking their horns might frighten the person on crutches. C) Drivers at the rear felt empathy for the confederate, which inhibited their aggression. D) Drivers at the rear forgot all about their own troubles. E) Drivers at the rear were given a dispositional attribution for the lead driver's hesitation.
