GMAT Critical Reasoning (CR) | Re: Lawrence County has seven county run hospitals

I think the key-phrase to distinguish between C and D is : "fewest negative health consequences for citizens of the county."

C could be a preference of the citizens due to many reasons. It may not necessarily mean that they provide better health benefits than remaining 6.

while D states the above implicitly. Hence D should not be closed to avoid -ve health consequence.
