Answer: The realistic conflict theory.
Explanation: This theory suggests that prejudice arises from competition between groups for limited resources, such as jobs, money, or land. In this case, Jay's prejudice toward a minority group is based on his perception that they are taking all the jobs, which creates a sense of competition and conflict between the two groups. His belief that he is a victim and blaming the minority group for his problems is a common response to this type of conflict.
