The most likely answer to this problem would be A. correct spelling, grammar, and punctuation.
This is on the grounds, of course, that the names utilized in the print advertisements especially to the names of the product and company are all in the standard grammar and spelling. When this is not given enough attention, it would immediately give the target audience the idea of incompetency such to an extent that it would consider the product and/or the company worthless. Having many different fonts, colors, and graphics would only create inconsistency and would irritate the audience. Spilling all the beans would only result to the diminishing of the interests of the audience. References that appeal to teenagers would be situational since it is not at all times that the target audience would be teenagers or the like.
