Final answer:
The correct answer is option c. a positive prejudice.
Step-by-step explanation:
In the scenario provided, Samantha's behavior towards her college football team and referees is an example of c. a positive prejudice. When she expresses a favorable opinion towards the players because they are part of her team, and displays anger towards a referee making what she perceives as a bad call against her team, Samantha is exhibiting an in-group bias. This type of bias is characterized by preferential treatment and positive attitudes towards members of one's own group over those of outsiders.
In this case, her college football team is her in-group, and the referee may be seen as part of an out-group. While stereotypes, prejudice, and discrimination are more commonly discussed in the context of negative impacts, they can also manifest as favorable treatment and feelings towards individuals based on their association with a group to which we belong.
