The correct answer highlights the point at which a senior citizen gains access to Medicare Supplementary Medical Insurance Plan, known as Part B, which generally coincides with their enrollment in Part A. When an individual becomes eligible for Medicare, they typically have the option to enroll in both Part A and Part B. Part A covers hospital care, while Part B covers outpatient services, physician visits, preventive care, and other medical services.

Medicare Supplement Plan, often referred to as Medigap, is designed to cover the out-of-pocket costs that are not paid by Medicare, such as coinsurance and copayments. Seniors usually need to enroll in Part B to be eligible for these supplemental insurance plans.

It's also essential to understand that simply reaching a certain age does not trigger automatic enrollment into Part B; individuals must actively enroll during their initial enrollment period or qualify for a special enrollment period. Therefore, the correct moment for a senior citizen to have access to the supplementary coverage aligns with their enrollment in Part A, as that sets the foundation for overall Medicare coverage.
