Mourdet Wineryanville Winery's new wine was introduced to compete with our most popular wine, which is sold in a distinctive tall, black bottle.Danville uses a similar bottle.Thus, it is likely that many customers intending to buy our wine will mistakenly buy theirs instead.

Danville Winery:Not so.The two bottles can be readily distinguished:the label on ours, but not on theirs, is gold colored.

Which of the following, if true, most undermines Danville Winery's response?

(A) Gold is the background color on the label of many of the wines produced by Danville Winery.

(B) When the bottles are viewed side by side, Danville Winery's bottle is perceptibly taller than Mourdet Winery's.

(C) Danville Winery, unlike Mourdet Winery, displays its wine's label prominently in advertisements.

(D) It is common for occasional purchasers to buy a bottle of wine on the basis of a general impression of the most obvious feature of the bottle.

(E) Many popular wines are sold in bottles of a standard design.

D是最适合的选项，但是我想问为什么A不对？

我的理解：
M说两种瓶子很像，消费者容易混淆
Danville说其实瓶子是有区别的,我们有金色的标志，他们没有

A选项说他们的瓶子很多标志以金色做背景，结合Danville说的我们瓶子有金色的标志，所以瓶子们还是很容易混淆的，weaken了Danville 说的瓶子是有区别的
