Adeline Watts · Answer 1

C is biased because the people were paid to evaluate the car. They are more likely to say better things about it than if they weren't paid.

Kareem Duarte · Answer 2

I believe it is B. The meaning of bias is prejudice in favor or against someone or a group compared to another in an unfair way. Many can have a one sided opinion about something such as who is going to win the race. However, choosing different cheese is more of an opinion showing which they prefer more than being bias.
