    Certain items--those with that hard-to-define quality
    called exclusivity--have the odd property, when they
    become available for sale of selling rapidly even
    though they are extremely expensive. In fact, trying to
    sell such an item fast by asking too low a price is a
    serious error, since it calls into question the very thing
    ---exclusivity--that is supposed to be the item's chief
    appeal. Therefore, given that a price that will prove to
    be right is virtually impossible for the seller to gauge
    in advance, the seller should make sure that any error
    in the initial asking price is in the direction of setting
    the price too high.

    The argument recommends a certain pricing strategy
    on the grounds that

   (A) this strategy lacks a counterproductive feature of
       the rejected alternative
   (B) this strategy has all of the advantages of the
       rejected alternative, but fewer of its disadvantages
   (C) experience has proven this strategy to be superior,
       even though the reasons for this superiority elude
       analysis
   (D) this strategy does not rely on prospective buyers'
       estimates of values
   (E) the error associated with this strategy, unlike the
       error associated with the rejected alternative, is
       likely to go unnoticed
