Which of the following is a primary role of the FDA?

The primary role of the FDA (Food and Drug Administration) is to protect public health by regulating the safety and efficacy of foods, medications, and other products. One crucial aspect of this role is providing guidelines for animal drugs, which encompasses overseeing the approval process for veterinary medications and ensuring that these drugs are safe and effective for animal use. By establishing these guidelines, the FDA helps to ensure that drugs administered to animals do not pose risks to animal health or, subsequently, to human health through the food chain.

While monitoring drug pricing, delivering comprehensive cancer treatment protocols, and ensuring the bioequivalence of therapies are important topics within the broader context of healthcare and drug regulation, they are not the primary functions of the FDA. The focus on animal drug guidelines falls squarely within the FDA's mandate to oversee products that impact health and safety.
