What is Medicare aimed at providing coverage for?

Medicare is specifically designed to provide health coverage primarily for elderly individuals, typically those aged 65 and older. Additionally, it extends coverage to certain disabled individuals under age 65 who meet specific criteria. This makes the focus of Medicare on these two groups—elderly and qualifying disabled persons—clear and distinctive.

In contrast, the other options identify populations that are not the target demographic for Medicare. Individuals with temporary disabilities may require assistance from other programs, such as Social Security Disability Insurance (SSDI), which is not the primary focus of Medicare. Low-income families are more likely to qualify for Medicaid, which addresses needs based on income level rather than age or disability status. Similarly, Medicare does not primarily cover children under the age of 18; this demographic generally has access to other insurance plans or Medicaid, depending on family circumstances. Therefore, option C accurately captures the essence of Medicare's intended coverage.
