87.In an effort to reduce their inventories, Italian vintners have cut prices; their wines have been priced to sell, and they are.

(A)have been priced to sell, and they are

(B)are priced to sell, and they have

(C)are priced to sell, and they do

(D)are being priced to sell, and have

(E)had been priced to sell, and they have

这里答案选择C，不理解什么意思，这个they代表的是什么，怎么都感觉句子像是没有说完似的。求解。谢谢！

为了减少存货，意大利酒商已经降低了价格。他们的酒被标价出售，他们也确实卖出去了。
根据代词 指代对象要一致，they 应该指代 vintners

我也在纠结这题，正确选项中do指代sell，但前句谓语是are，为了平行，
为什么不是“are priced to sell, and they are”呢?   

~~求指正~~

我觉得和they do 的do平行的是sell 吧

bradfordchens

说的对，是sell
