菜鸟请教一道OG11里面的81题~~

81.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

The answer is C.

我做的时候选是选对了，但是是看语法平行角度选的，在网上差了几个帖子说这个题的 还是没有明白到底这句话什么意思？

请大家能不能给我看看，这句话到底什么意思啊~~~

菜鸟不胜感激！

意大利酒商为了减少库存于是减价了。他们的就定价出售，于是酒的库存就少了。

分号后面：their跨分号指代vintners，第二个they指代their wines。
