Advertiser: The revenue that newspapers and magazines earn by publishing advertisements allows publishers to keep the prices per copy of their publications much lower than would otherwise be possible. Therefore, consumers benefit economically from advertising.
Consumer: But who pays for the advertising that pays for low-priced newspapers and magazines? We consumers do, because advertisers pass along advertising costs to us through the higher prices they charge for their products.
Which of the following best describes how the consumer counters the advertiser’s argument?
(A) By alleging something that, if true, would weaken the plausibility of the advertiser’s conclusion
(B) By questioning the truth of the purportedly factual statement on which the advertiser’s conclusion is based
(C) By offering an interpretation of the advertiser’s opening statement that, if accurate, shows that there is an implicit contradiction in it
(D) By pointing out that the advertiser’s point of view is biased
(E) By arguing that the advertiser too narrowly restricts the discussion to the effects of advertising that are economic

请问各位NN, 为什么B不对呀? 答案是A, 是不是因为B说的是: 置疑广告商说的东西真实性, 而A是削弱合理性.

b means that consumers would deny the fact that the reveneve keeps the prices per copy much lower. In fact, the consumers don't deny the fact; they just give another fact to refute that advertiser' conclusion.

E为什么不对呢? advertisers只说了广告能使报纸,杂志的发行价很低(即effects that are economic),而没说广告会使消费者购买的产品价格更高.正好和E所说的思路一致啊
