Answer:
D. Bandwagon advertising

Bandwagon advertising is a type of propaganda advertising technique that is employed to sway the emotions of the audience to get them to purchase a particular product or service simply because many other persons are using such. So, the audience, in a bid to join crowd, they will willingly purchase such product or services on the ground that it is tested and trusted by many users.
