B. Aggress against lower-class residents of the town
Correct.
B Is correct because frustration aggression theory predicts that when
individuals are frustrated and cannot aggress against the source of their
frustration, they will attack less powerful groups. In this case
the lower-class residents would serve as a scapegoat, especially if many
of them are a different ethnicity or religion than the workers. (See Myers,
359-360; Aronson, 337-340)
