Sales of telephones have increased dramatically over the last year. In order to take advantage of this increase, Mammoth Industries plans to expand 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 Industries cannot increase its sales of telephones by adopting the plan outlined above? 

(A) Although it sells all of the telephones that it produces, Mammoth Industries' share of all telephone sales has declined over the last year.

(B) Mammoth Industries' average inventory of telephones awaiting shipment to retailers has declined slightly over the last year.

(C) Advertising has made the brand name of Mammoth Industries' telephones widely known, but few consumers know that Mammoth Industries owns this brand.

(D) Mammoth Industries' telephone is one of three brands of telephone that have together accounted for the bulk of the last year's increase in sales

e说, 去年产品降价了, 结果销售还是下滑了, 说明他家的东西不好卖, 今年再扩大产能不是找死吗?

c说的是公司对于品牌的所有权和公众对于这一事件的了解程度, 这和产品卖不卖的好有啥关系?
