Which group is eligible for Original Medicare based on age and disability?

The correct choice identifies a comprehensive set of criteria for eligibility for Original Medicare. Individuals are typically eligible for Original Medicare when they reach the age of 65, which is a primary qualifier based on age. Additionally, it includes those under the age of 65 who have been receiving Social Security Disability Insurance (SSDI) for at least 24 months. This duration is significant because it ensures that individuals have met a minimum threshold of disability benefits before qualifying for Medicare.

Moreover, the option encompasses persons diagnosed with End-Stage Renal Disease (ESRD) or Amyotrophic Lateral Sclerosis (ALS), which allows for immediate eligibility for Medicare regardless of age. This reflects Medicare's adaptability to cover those with severe health conditions affecting various age groups. Therefore, the selection highlights a thorough understanding of the criteria established for Original Medicare, effectively recognizing those who fit within the various eligibility brackets.
