Final answer:
Medicare Part A specifically covers inpatient hospital stays, not outpatient services, doctor's fees, or prescription drugs. Coverage for doctors' fees and outpatient services is provided under Medicare Part B, while prescription drugs are covered by Medicare Part D.
Step-by-step explanation:
Medicare Part A covers c) inpatient hospital stay. This part of Medicare pays for hospital charges for eligible individuals and is funded by payroll deductions and matching contributions from employers. It includes coverage for services such as semi-private rooms, meals, general nursing, and other hospital services and supplies. However, Medicare Part A does not cover outpatient services, doctor's fees, or prescription drugs. These are typically covered under Medicare Part B, which is the optional medical insurance for health care costs outside of hospital stays, and Medicare Part D, which provides prescription drug coverage.
