Which of the following groups is NOT eligible for low-cost health insurance coverage?

The group that is not eligible for low-cost health insurance coverage is high-income adults. Low-cost health insurance programs are typically designed to help individuals and families who may not have sufficient financial resources to afford standard health insurance premiums. These programs are aimed at low-income individuals, including pregnant women and children, who often require additional support for healthcare needs.

Pregnant women and children are generally included in low-cost health insurance coverage initiatives because their healthcare needs can be more significant, and ensuring they have access to necessary medical services is a priority for public health. Adults aged 19-64 who are not pregnant may also be eligible for low-cost coverage, especially if they meet specific income criteria.

High-income adults, however, are not the target demographic for low-cost health insurance programs, as they typically exceed the income limits established for eligibility. Therefore, this group is expected to be able to afford standard health insurance options.
