Answer: B) A pickup truck
Explanation:
Reference groups enable comparison because they are sort of like role models to people because people use them to evaluate their lives and certain choices they make. As a result, marketers compare people to these groups and target these groups to be able to sell products so that their influence will lead others to buy as well.
Pickup truck reference groups are very strong and can influence what sorts of trucks are considered great quality. This is mostly down to the fact that producing pickup trucks is a bit of a concentrated market with few major players so the endorsement of pickup truck reference groups of a pickup, is a significant thing.
