but on further analysis, I found that only the verbs that are logically parallel should appear in parallel structure.

E: 'requiring' and 'spending' are parallel in the modifier, but this will imply that the plans themselves spend time with patients that doesn't make sense.

So, D is correct

the eror of A , B and C is corrected and ....bcoz spending is modifying sub of previous clause i.e doctors.....correct

(E) that impose stricter limits on medical services, requiring doctors to see more patients and spending
impose and requiring is not parallel
