Whichof the following most logically completes the argument below?
Twentypercent of the stores in Morganville's downtown shopping district will failwithin five years because they will be competing directly with the SaveMartdiscount department store newly opened in East Morganville.  The downtown shopping district has lostbusiness at this rate before and has always completely rebounded.  Confidence that it will rebound again fromthe losses it is now about to suffer is ill founded, however, because__________.
A. the stores likely to be put out ofbusiness by direct competition from SaveMart are the downtown shoppingdistrict's anchor stores, on whose ability to draw shoppers many of the otherdowntown stores depend
B.the bus line that has long connected the downtown area of Morganville with EastMorganville has a tradition of carrying shoppers who reside in East Morganville into downtown Morganville to shop
C.when the downtown shopping district has rebounded before, the business premisesof a failed business were typically taken over by a business of the same kindas had been there before
D.SaveMart's business plan for the East Morganvillestore is based on earning low profits, if any, during the first five years ofthe store's existence
E.it is conceivable that the downtown shopping district could shrinksubstantially without collapsing altogether
我想请问一下B为什么不对，我觉得原来在downtown买东西的East Morganville居民现在不再到downtown买东西了，会直接在SaveMart买东西，这样downtown就不会好转呀，这么想不对吗？

The bus line has existed for years during which the downtown shopping districts has undergone up and downs. Therefore, an existing bus line cannot enable the author's argument.
