Option A.
Step-by-step explanation:
The evolution of the US healthcare system is a product of both free markets and government intervention.
Initially, the healthcare system in the United States operated as a free market, with little government involvement.
However, over time, the government has taken on a larger role in regulating and financing healthcare.
Examples of government intervention in the healthcare system include programs like Medicare and Medicaid, which provide health insurance coverage for seniors and low-income families respectively.
