Many buyers of fashion clothing are inclined to contribute to charitable organizations, and are more likely to purchase clothing from companies that donate a portion of their profits to charity. Next weekend, a variety of fashion clothing retailers will hold sample sales at a downtown event; the event's organizers plan to hand out flyers listing which of the retailers donate to charity from their profits, in the hope of increasing those companies' sales at the event.

Which of the following, if true, most calls into question the appropriateness of the organizers' plan?

(A) The cost to the organizers of designing and printing the flyers is equivalent to half an average day's worth of sample-sale profits for one of the retailers at the event.

(B) Many of the retailers who donate profits to charity do so in order to garner tax breaks, rather than for purely altruistic reasons.

(C) Among the retailers who will hold sample sales at next week's event, those that donate a portion of their profits to charity far outnumber those that do not.

(D) Of the retailers at the event that donate a portion of their profits to charity, most have publicized those donations extensively in their advertising.

(E) Many of the retailers who donate a portion of their profits to charity vary that portion from season to season, allocating a greater portion of their profits to charity during peak sales seasons.
