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E.        During the period, consumer-electronics retailers sold remaining units of Denoma’s superseded models at prices that were deeply discounted from those models’ original prices.

就是想问为什么大家都说B是无关项呢？我的逻辑是，D的竞争对手收入降低得更厉害，说明这是一个industry-wide的问题，整个行业都面临着下滑，而D由于产品很创新很优秀，所以在整体的颓势中下降得比竞争对手更慢些。这难道不能解释题目中的surprising results吗？难道是我做consulting的case interview做多了想得太多......？

求大牛指导！！感激不尽！!

不是想得太多，是没看明白题目。
surprising result指的是：零售商卖D牌的销售收入上升，但D自家的销售收入下降。
所以B完全无关。
