The correct answer reflects that individuals who are eligible for Medicare and do not enroll when they first become eligible may still have the opportunity to enroll in certain parts of Medicare at any time. Specifically, for Medicare Part A, individuals can enroll without any restrictions as long as they meet the eligibility criteria, which is generally based on having worked and contributed to Medicare through payroll taxes for at least 10 years.

This means that while there may be specific time frames and repercussions related to not enrolling in Part B or other aspects of Medicare, Part A does indeed allow for continuous enrollment as long as eligibility is maintained. Thus, Salvador, who did not enroll in Medicare upon his initial eligibility, still retains the ability to enroll in Part A at any time, assuming he meets the basic qualification criteria.

This distinguishes it from the other options, where factors like lost eligibility, requiring a special enrollment period, or limitations on enrolling in Part B whenever ready do not apply to Part A.
