Which word refers to a person engaged in a practice such as medicine or law?

• A. Potent
• B. Precipitate
• C. Practitioner
• D. Precede

Answer: (C)

A word for a person who practices a profession. Practitioner fits perfectly because it names someone who actively works in a field, especially professions like medicine or law. It signals that the person is engaged in applying skills and knowledge in real life, not just learning about the field. The other words have different meanings: potent means strong or powerful, precipitate means to act hastily or a chemical drop, and precede means to come before in time or order. So practitioner is the only term that correctly identifies the person as a professional in a practice.
