Final answer:
Pharmacy technicians in the United States must be registered or licensed by the State Board of Pharmacy (SBOP), not the FDA, which regulates the safety and efficacy of medicines sold by pharmacies.
Step-by-step explanation:
In the United States, pharmacy technicians are often required to be registered or licensed before they can perform the duties of a pharmacy technician. This requirement for pharmacy technicians to be registered or licensed is mandated by the State Board of Pharmacy (SBOP). While the Food and Drug Administration (FDA) is responsible for regulating the medicines that pharmacies sell to ensure their safety and efficacy, it is not the agency that mandates the registration or licensing of pharmacy technicians. The answer to the student's question is B. State Board of Pharmacy (SBOP).
