恳请nn帮忙分析一下这题

iselibra

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
看了og后面的解释还是觉得云里雾里，记得分号前后的两句的结构应该是相同的，
难道时态不是么？主句用的完成式，从句也应该用完成式才对巴。
还有为什么,and they do的do就一定指sell呢，有什么规律么？
谢谢！

偶选A
D/E 明显错误
B中 be+and+have
C中 be+and+do

歧义
如果选A，and they are重复表示强调，正确
如果选c，and they do/sell，the wines are priced to sell, and they sell，表示结果，正确

这个能再讲讲吗？这题我也觉得好古怪。不明白。

可是答案是C啊

分号后面是一个句子，they ..., and ...   我觉得and前后应该用同一种时态。
(A) have ..., and they are
(B) are ..., and they have
(C) are ..., and they do
(D) are ..., and have
(E) had ..., and they have

所以只有C能选
不知道这么做对不对，请nn指点

这么说好像有点味道
不过and前后却未必要同一个时态巴？
