Why cant it be B?

Im sorry, I meant D and E

D: For restaurants, utilizing direct–mail marketing requires the names, addresses, and menu selections of at least some customers. (this is the answer choice I selected, but on the question it is in a different order)

Hello. I am not an instructor but my understanding might help: I was also initially tempted by "For restaurants, utilizing direct–mail marketing requires the names, addresses, and menu selections of at least some customers." I may be looking too deeply into it, but if the aforementioned was the case, then NO restaurants would be able to utilize direct-mail marketing, since in the beginning we are told that pizzerias are the only ones that record this information. This is not was the argument is saying. Instead the conclusion is that pizzerias are the BEST at this type of marketing, not that they are the only ones who use it.
