The correct answer is B. ARP-DRG. The ARP-DRG (All-Patient Refined DRG) system was adopted by Medicare in 2008 to reimburse hospitals for inpatient care provided to Medicare beneficiaries. This system is designed to classify inpatient hospital cases into groups with similar clinical characteristics and similar costs.

Option A, AP-DRG, is not the correct choice as Medicare adopted the ARP-DRG system in 2008, not the AP-DRG system.

Options C and D, Ambulatory Surgical Center Payment Rate and Ambulance Fee Schedule, are not relevant to the DRG system used for inpatient care reimbursement by Medicare in 2008. The Ambulatory Surgical Center Payment Rate relates to reimbursement for services provided in ambulatory surgical centers, and the Ambulance Fee Schedule relates to reimbursement for ambulance services, not inpatient care provided by hospitals.
