一道CR求指点

Because postage rates are rising, Home Decorator magazine plans to maximize its profits by reducing by one half the number of issues it publishes each year. The quality of articles, the number of articles published per year, and the subscription price will not change. Market research shows that neither subscribers nor advertisers will be lost if the magazine’s plan is instituted.

Which of the following, if true, provides the strongest evidence that the magazine’s profits are likely to decline if the plan is instituted?

(A) With the new postage rates, a typical issue under the proposed plan would cost about one-third more to mail than a typical current issue would.
（B) The majority of the magazine’s subscribers are less concerned about a possible reduction in the quantity of the magazine’s articles than about a possible loss of the current high quality of its articles.
(C) Many of the magazine’s long-time subscribers would continue their subscriptions even if the subscription price were increased.
(D) Most of the advertisers that purchase advertising space in the magazine will continue to spend the same amount on advertising per issue as they have in the past.
(E) Production costs for the magazine are expected to remain stable.

为什么分析的时候subscribers are a non-factor?为什么不能选A和D？
求大神指点这道题拿到手正确的做题思路？
谢谢啦！
