Sales of telephones have increased dramatically over the last year. In order to take advantage of this increase, Mammoth plans to expend production of its own model of telephone, while continuing its already very extensive advertising of this product.
Which of the following, if true, provides most support for the view that Mammoth cannot increase its sales of telephones by adopting the plan outlined above?
A.Although it sells all of the telephones it produces,Mammoth's share of all telephones sales has declined over the last year.
B.Mammoth's average inventory of telephones awaiting shipment to retailers has declined slightly over the last year.
C.Advertising has made the brand name of Mammoth's telephones widely known, but few consumers known that the Mammoth owns this brand.
D.Mammoth's telephone is one of the three brands of telephone that have together accounted for the bulk of the last year's increaase in sales.
E.Despite a slight decline in the retail price, sales of Mammoth's telephons haave fallen in the last year.
讲义给的答案是E，但我选了D，其它选项排的也很辛苦。。。望牛人讲解下，谢谢

电话的销售量去年升高，M计划增加电话产量，并且继续大量投入广告。

问那个选项说明M不能通过上述策略盈利。（削弱）

A.share of all telephones sales .市场占有率，无关，只要sales升高就可盈利。

B.average inventory of telephones  存货，无关

C.brand name of Mammoth's telephones知名度以及顾客是否知道M拥有这个品牌 与能否盈利无直接关系

D. M是去年sales上升的牌子之一，该策略可行，支持。

E在说：尽管价格微幅下调，去年的销量还是下降了。这就说明在整体市场“Sales of telephones have increased dramatically over the last year. ”的情况下，MI的销量都下降了，即使今年整体市场形势还是很好，但MI的市场销量未必好，那么扩大生产也未必必要。
