Answer:
B) straight-sell copy
Step-by-step explanation:
In marketing, copy refers to an original message created a company (either the manufacturer or an advertising company) that is meant to induce consumers into purchasing the product or service offered by the company. It is called copy because advertisements can also be copyrighted.
When an advertisement uses a straight sell copy, they are laying out facts about the product. Of course they do in an elegant and attractive manner, like saying "Falcon owners worry 20 to 60 % less". It means that Falcon airplanes allegedly consume 20-60% less fuel. Since the company is providing facts, they must be able to prove them to be right.
In this case, the Federal Trade Commission (FTC) prohibits false advertising, so we can expect that the airplane actually uses fewer fuel than the competition. If it wasn't so, then any competitor could file a complaint and the advertisement would be withdrawn from media outlets and the company fined.
Straight sell copy is used to highlight the good qualities and characteristics of your product compared to your competition, that is why it is generally used by brands that can prove that their products are better or at least as good as their competitors.
