一道语法题那里没人回答，大家帮忙看看

Among lower-paid workers, union members are less likely than nonunion members to be enrolled in lower-end insurance plans imposing stricter limits on medical services and requiring doctors to see more patients, and spend less time with each.

A.    imposing stricter limits on medical services and requiring doctors to see more patients, and spend

B.    imposing stricter limits on medical services, requiring doctors to see more patients, and spending
            

C.    that impose stricter limits on medical services, require doctors to see more patients, and spend
            

D.    that impose stricter limits on medical services and require doctors to see more patients, spending

E.     that impose stricter limits on medical services, requiring doctors to see more patients and spending

答案给的是D，但是这样spending物品觉得很奇怪，怎么就和前面的不对称了呢？

C有什么问题呢

谢谢

LZ主要要看这句话的意思呀，不能只看平行结构

spending是针对医生来说的，让他们看更多的病人，但在每个病人上少花点时间

c的话语意就很奇怪了

这道题目要分析逻辑意思！

that后面的impose和require是并列的，一起修饰plans，而后面的spending不是和前面的两个动词并列的，这里的spending用V-ing形式表示伴随结果，后面的内容是require doctors to see more patients的结果！
