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
答案选D，但是D中spending做see的伴随状语，为什么spending这里做从句的一个非谓语动词的伴随状语？还有spending的动作发出者doctor也并非主句主语。这是神马情况？可以这样用的么？
还有A答案是不是去掉逗号就正确了？

同问，我也觉得spend的发出者是doctor，但是这个很明显指代有嫌疑。
