Medicaid primarily provides healthcare coverage for which group of individuals?

Medicaid is a government program specifically designed to provide healthcare coverage to low-income individuals and families. This program supports a diverse range of populations, including low-income children, adults, elderly individuals, and people with disabilities. It aims to ensure access to necessary medical care for those who might otherwise be unable to afford it, thus promoting overall public health.

The program's broad eligibility criteria allow it to cover various vulnerable groups, reflecting the intent to support individuals and families facing financial hardships. This includes not just the elderly, but also children and individuals with disabilities who may require various forms of medical assistance.

In contrast, the other options focus on groups that do not align with Medicaid's intended demographic. For instance, high-income individuals and families typically do not qualify for Medicaid, as the program is specifically for those with limited financial resources. Limiting coverage to only elderly individuals or individuals over the age of 65 neglects the program's inclusivity regarding families and younger individuals in need of assistance. Therefore, option B accurately represents the comprehensive nature of Medicaid, which is crucial to understanding the program's importance in the healthcare system.
