Medicare, the United States government's health insurance program for the elderly and disabled, covers the full cost of home health care, but not with other nonhospital services where 20 percent of the costs must be paid by beneficiaries.

A. but not with other nonhospital services where 20 percent of the costs must be paid by beneficiaries.
B. but not of other nonhospital services, making beneficiaries pay 20 percent of the costs.
C. but not of other nonhospital services, for which beneficiaries must pay 20 percent of the costs.
D. which is unlike other nonhospital services in that 20 percent of the costs must be paid by beneficiaries.
E. which is unlike other nonhospital services that make beneficiaries pay 20 percent of the costs.
In A, B, D and E, it is not crystal clear exactly WHAT costs are implied by 20 percent of the costs.
Only C makes the intended meaning crystal clear:
C: Medicare covers the full cost of home health care but not of other nonhospital services, for which beneficiaries must pay 20 percent of the costs.
Here, which refers to other nonhospital services, making it crystal clear that beneficiaries must pay 20 percent of the costs FOR OTHER NONHOSPITAL SERVICES.

The correct answer is C.
