Which advertising technique demonstrates consumer trust through the portrayal of multiple users?

The choice that accurately represents an advertising technique that demonstrates consumer trust through the portrayal of multiple users is bandwagon advertising. This method relies on the concept that if a large number of people are using or endorsing a product, others are more likely to want it as well. The portrayal of multiple users implies popularity and acceptance, which can build trust among potential consumers.

When multiple users are showcased enjoying a product or service, it reinforces the idea that it is widely accepted and valued, which can appeal to individuals who may be uncertain about a purchase. This social proof can be powerful, as prospective buyers often look to the experiences of others to gauge the reliability and effectiveness of what they are considering.

Other advertising techniques like endorsements may highlight a single individual's approval or experience with a product, but bandwagon advertising specifically emphasizes group acceptance, making it a potent tool for cultivating consumer trust.
