Why A is correct
Individuals who are already receiving Social Security retirement benefits are automatically enrolled in Medicare Part A when they reach age 65, because their entitlement to Social Security establishes work credits and Medicare eligibility. They are also automatically enrolled in Part B unless they affirmatively decline it, since most beneficiaries want the medical coverage. The examination objectives describe automatic eligibility at age 65 for citizens and legal residents entitled to Part A (AH-III.D.1b), making this passive enrollment outcome a commonly tested point.
Why the other options are wrong
- B) No separate application is needed when Social Security benefits are already in payment; enrollment is automatic.
- C) Part D is voluntary and separate; automatic enrollment covers Parts A and B, not D.
- D) Enrolling at first eligibility avoids any late-enrollment penalty, so automatic enrollment means no penalty applies.
