Answer & full 3-part explanation (select an option above, or peek)
Why A is correct
Part D enrollment is tied to Medicare entitlement: a beneficiary must have Part A and/or be enrolled in Part B to join a stand-alone Prescription Drug Plan or a Medicare Advantage plan with drug coverage. This linkage is the basic eligibility gate for Part D. Age 80, home ownership, and disability are all irrelevant to Part D eligibility — someone under 65 can enroll if entitled to Part A through a disability, and a 65-year-old with Part A and B is eligible regardless of housing status or disability documentation.
Why the other options are wrong
- B) Part D eligibility is not age-80-gated; any Medicare-entitled beneficiary can enroll.
- C) Home ownership has no bearing on Part D eligibility.
- D) Disability matters only as a route to Part A entitlement, not as a standalone Part D requirement.
Memory hook
Part D needs a foot in Medicare's door — Part A or Part B.
