12. Approximately two hundred brands of personal computers are being manufactured, but we currently limit our inventory to only the eight most popular brands. We plan to increase greatly the number of computers we sell by expanding our inventory to include the ten best-selling brands.
Which of the following, if true, points out a major weakness of the plan above?
(A) The capabilities of three most popular personal computers add to be approximately equivalent, with no brand having consistent superiority in all respects.
(B) The seven most popular brands of personal computers account for almost all computers sold.
(C) As the users of personal computers become more sophisticated, they are more willing to buy less well-known brands of computers.
(D) Less popular brands of computers often provide less profit to the retailer because prices must be discounted to attract customers.（B）
(E) The leading brand of personal computer has been losing sales to less popular brands that offer similar capabilities for less money.
这道题中C 和E选项很迷惑，偶觉得也是weakness？记得有位前辈说，SC是选优，而CR是选择正确的，言下之意就是其他的都应该是错的！此原则在这题如何理解？
