小同学我求助GWD-TN-9一道逻辑题。

GWD-12-Q22:A C
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E.    During the period, consumer-electronics retailers sold remaining units of Denoma’s superseded models at prices that were deeply discounted from those models’ original prices.

答案是C，我选的A。
有人可以帮我解析一下这道题目吗？我还是觉得A比较合理，是不是我的理解有偏差？

题目说这个公司的总销售额下降了，但是这个公司的报告说Denoma models的销售额实际上是增长了的，问discrepancy?

A这里说了此公司为了教受公众这个新Denoma models的功能，而增加了广告的投入----此处有三种可能：1.就是你理解的导致了公司销售额的增加；2。公司销售额不变；3.公司销售额依旧是减少了；
因此此项不能确定的说明原因

C说因为一大部分Denoma’s revenue是因为买零件给消费电子的制造商，也就说明了那部分增加的销售额的原因了

楼上关于A错的解释很清楚了。
另外，sales revenus of Denoma models 包括零售和批发（工厂采购,B2B）原文只说零售销售下降，那如果批发销售额上升，也可以使得整个sales revenus 上升。

哇，sunluning0，我怎么都想不到批发这个factor，哈哈。
anyway，谢谢两位啦。
