Which authority controls the licensing of physicians in each state?

The state medical board is the correct authority responsible for the licensing of physicians in each state. Each state has its own medical board that operates under state law and regulations. These boards are tasked with overseeing the practice of medicine within the state, which includes issuing licenses to qualified medical professionals, enforcing standards of practice, and addressing complaints against physicians. By maintaining a rigorous licensing process, state medical boards help ensure that physicians meet the required educational and ethical standards, ultimately safeguarding public health and welfare.

The other options, while they may play roles in public health or policy, do not have the specific function of licensing physicians. The Department of Health focuses more on public health initiatives and safety regulations rather than individual licensing. The Governor's office may influence healthcare policy but does not directly issue medical licenses. The American Medical Association serves as a professional organization advocating for physicians but does not have the authority to license them.
