What does ACA stand for?

The term ACA stands for Affordable Care Act, which is a significant piece of legislation passed in the United States in 2010 aimed at reforming healthcare. This law was designed to increase health insurance coverage, reduce healthcare costs, and improve the quality of care across the nation. It introduced measures such as the Health Insurance Marketplace, Medicaid expansion, and various protections for consumers against discrimination by insurance companies.

While the other options may seem plausible, they do not accurately capture the widely recognized meaning of ACA in the context of healthcare and legislation. The Affordable Care Act has played a crucial role in shaping health policy and access to care, making it a crucial reference point in discussions about American healthcare reform.
