这个B感觉有点irrelevant呀？

Over the past five years, the price gap between name-brand cereals and less expensive store-brand cereals has become so wide that consumers have been switching increasingly to store brands despite the name brands’ reputation for better quality.To attract these consumers back, several manufacturers of name-brand cereals plan to narrow the price gap between their cereals and store brands to less than what it was five years ago.



Which of the following, if true, most seriously calls into question the likelihood that the manufacturers’ plan will succeed in attracting back a large percentage of consumers who have switched to store brands?



A.There is no significant difference among manufacturers of name-brand cereals in the prices they charge for their products.

B.Consumers who have switched to store-brand cereals have generally been satisfied with the quality of those cereals.

C.Many consumers would never think of switching to store-brand cereals because they believe the name brand cereals to be of better quality.

D.Because of lower advertising costs, stores are able to offer their own brands of cereals at significantly lower prices than those charged for name-brand cereals.

E.Total annual sales of cereals—including both name-brand and store-brand cereals—have not increased significantly over the past five years.

这个B虽说算是个他因，可是如果大家会第一时间考虑这种他因吗，感觉不太relevant呢~ 求解释~

挺明显的 如果消费者本来就对strore brand的品质满意 那么价格不是他们考虑的首要因素了呀
