Medicaid is a program primarily intended for which of the following groups?

Medicaid is primarily designed to provide healthcare coverage to individuals and families who cannot afford to pay for medical care. This includes various groups, such as low-income individuals, people with disabilities, pregnant women, and families with children. The program seeks to ensure that those in financial need have access to necessary medical services, which aligns with its goal of reducing healthcare disparities and supporting vulnerable populations.

The program's income eligibility varies by state and is typically based on the Federal Poverty Level, reinforcing its focus on helping those whose financial situation makes it difficult to access adequate healthcare services. Thus, the correct response highlights Medicaid’s fundamental purpose of aiding those unable to afford healthcare.
