Which of the following is classified as a government insurer?

The classification of Social Security as a government insurer stems from its role in providing financial assistance and benefits to individuals primarily in the realms of retirement, disability, and survivor's benefits. Social Security is administered by the federal government and is funded through payroll taxes collected under the Federal Insurance Contributions Act (FICA). Unlike private insurance companies, which operate for profit and offer various types of insurance products, Social Security is a social welfare program designed to provide basic economic security for individuals, particularly during retirement or in the event of disability.

The other options listed are all private insurance companies that operate within the marketplace, providing various forms of insurance products such as auto, home, health, and life insurance. These companies are not considered government insurers because they function independently of government funding and operate in a competitive environment, aiming to make a profit by underwriting risk and providing services to policyholders.
