This resultappears surprising, because electronics retailers report that although theiroverall sales were considerably lower than in the previous year, their salesrevenue from Denoma models actually grew, largely thanks to some innovative andpopular models that Denoma introduced. Whichof the following, if true, does most to explain the apparently surprisingresult? A.Because of the need to educate the public about its new models’ capabilities,Denoma’s advertising spending was higher than normal over the period. B.For the period at issue, Denoma’s major competitors reported declines inrevenue that were, in percentage terms, greater than Denoma’s. C.A significant proportion of Denoma’s revenue comes from making components forother consumer-electronics manufacturers. D.Unlike some of its major competitors, Denoma has no lines of business outsideconsumer electronics to provide revenue when retail sales of consumerelectronics are weak. E.During the period, consumer-electronics retailers sold remaining units ofDenoma’s superseded models at prices that were deeply discounted from thosemodels’ original prices. 此题选c
