16. The recent upheaval in the office-equipment retail business, in which many small firms have gone out of business, has been attributed to the advent of office equipment “superstores” whose high sales volume keeps their prices low. This analysis is flawed, however, since even today the superstores control a very small share of the retail market.

  Which of the following, if true, would most weaken
  the argument that the analysis is flawed?
  (A) Most of the larger customers for office
      equipment purchase under contract directly
      from manufacturers and thus do not participate
      in the retail market.
  (B) The superstores’ heavy advertising of their low
      prices has forced prices down throughout the
      retail market for office supplies.
  (C) Some of the superstores that only recently
      opened have themselves gone out of business.
  (D) Most of the office equipment superstores are
      owned by large retailing chains that also own
      stores selling other types of goods.
  (E) The growing importance of computers in most
      offices has changed the kind of office
      equipment retailers must stock.
这道题的答案是B，但是我觉得B并没有反对the argument that the analysis is flawed。
只是加强了前半部分的论述。但是其他的选项应该也都不对。请指教阿
