• A. A physician who has earned a Doctor of Medicine degree from an accredited allopathic medical school.
• B. A physician who has earned a Doctor of Dentistry degree.
• C. A nurse with a doctoral degree.
• D. A chiropractor with a specialized degree.

Answer: (A)

MD stands for Doctor of Medicine, which identifies a physician who earned that degree from an accredited allopathic medical school. This training focuses on conventional medicine and preparing physicians to diagnose and treat medical conditions in a standard medical framework. The other options describe different professions or degrees—dentistry uses a Doctor of Dentistry (DDS/DMD), a nurse with a doctoral degree holds a nursing doctorate (like DNP or PhD), and a chiropractor has a Doctor of Chiropractic—so they do not describe an MD. Thus, the description of a physician who has earned a Doctor of Medicine degree from an accredited allopathic medical school is the correct one.
