Which of the following best defines Medicaid?

Medicaid is best defined as a public assistance program for low-income individuals. This government-sponsored program provides health coverage to eligible individuals and families who meet certain income and other criteria. It aims to ensure access to necessary health services for those who might otherwise be unable to afford care, including children, pregnant women, and individuals with disabilities, in addition to the elderly.

Unlike a federal program for all citizens, which would imply universal coverage, Medicaid specifically targets low-income populations. It is also not limited to the elderly, as it provides services to a wide range of disadvantaged groups. Additionally, Medicaid is a public program rather than a private insurance option, distinguishing it from private insurance plans that individuals might purchase.
