[求助】GWD-12-Q22

Denoma, a major consumer-electronics maker, had a sizeable decline in sales revenue for its most recent fiscal year.  This result appears surprising, because electronics retailers report that although their overall sales were considerably lower than in the previous year, their sales revenue from Denoma models actually grew, largely thanks to some innovative and popular models that Denoma introduced.

Which of the following, if true, does most to explain the apparently surprising result?

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 in revenue that were, in percentage terms, greater than Denoma’s.

C.    A significant proportion of Denoma’s revenue comes from making components for other consumer-electronics manufacturers.

D.    Unlike some of its major competitors, Denoma has no lines of business outside consumer electronics to provide revenue when retail sales of consumer electronics are weak.

E.     During the period, consumer-electronics retailers sold remaining units of Denoma’s superseded models at prices that were deeply discounted from those models’ original prices.

选项C我没意见，是有道理的，但是我选择的是A，就不知道为什么错了！因为

利润其实是等于销售额再减去投入的，但是广告投入也算是投入啊....

请NN帮助

楼上的GG,那这个 sales revenue只是指的总共的销售额么？
