请教OG 11th 81

81.In a effort to reduce their inventories,Italian vintners have cut prices;their wines have been prices 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

答案C

这句话不是很理解，请教大家，后面的and they do指的是什么。。。

分词后面的句子应该是对前面句子的说明。前面一句的结构是因果关系，因为“要降低库存”所以“降价”。而后面的含义应该是“他们降价”所以“库存降低”。

所以把do代替的内容补足的话，我想应该是：

their wines are priced to sell, and they reduce their inventories.

你所说的they reduce their inventories中的they指的是什么呢？
