The right option is option B, Bandwagon Advertising. According to this advertising strategy people are more likely to accept a product if everyone else is doing so, and that is why it is also known as the copycat effect. A lot of studies have shown that humans are more likely to adapt their mindsets to the majority ones, and we would even accept a lie under social and peer pressure, thus bandwagon advertising is trying to make us buy something because it's popular and everyone else is doing so.
