Some airlines allegedly reduce fares on certain routes to a level at which they lose money, in order to drive competitors off those routes.However, this method of eliminating competition cannot be profitable in the long run.Once an airline successfully implements this method, any attempt to recoup the earlier losses by charging high fares on that route for an extended period would only provide competitors with a better opportunity to undercut the airline's fares.

Which of the following, if true, most seriously weakens the argument?

(A) In some countries it is not illegal for a company to drive away competitors by selling a product below cost.

(B) Airline executives generally believe that a company that once underpriced its fares to drive away competitors is very likely to do so again if new competitors emerge.

(C) As part of promotions designed to attract new customers, airlines sometimes reduce their ticket prices to below an economically sustainable level.

(D) On deciding to stop serving particular routes, most airlines shift resources to other routes rather than reduce the size of their operations.

(E) When airlines dramatically reduce their fares on a particular route, the total number of air passengers on that route increases greatly.
我觉得B、D都有削弱啊。
D说一旦决定stop，就转向其他route,言下之意就是即使你这个公司再涨价，被drive away的公司也不可能再回到这个原来的route来了啊。 D为什么不对？

我觉得d是无关选项吧，原文都没说停止服务某个航线，只是说对某些航线收取较低的费用…

这里的stop是从被drive away 的企业的角度讲的，这样理解的话呢？
