Correct Answer: C

Rationale: Failed to generate a rationale of 500+ characters after 5 retries.

Correct Answer: D

Rationale: The correct answer is 'a and c' (DEA and FDA) because both agencies jointly control prescription medications. The FDA approves and regulates the safety, efficacy, and labeling of all prescription drugs, while the DEA oversees controlled substances within prescriptions, managing schedules and distribution to prevent abuse. The Bureau of Dangerous Drugs is not a valid current agency; it's a historical reference, possibly confused with the DEA's predecessor. Choosing 'a' or 'c' alone omits half the oversight, and 'all of the above' includes an invalid option, making 'a and c' the accurate choice per U.S. regulatory framework.

Correct Answer: D

Rationale: All of the above' is correct because the FDA regulates purity and quality (consistency, contamination-free), identity (correct labeling), and strength (dosage accuracy) under its mandate to ensure drug safety and efficacy. 'Purity and quality' alone omits identity and strength. 'Identity' or 'strength' individually are incomplete. The FDA's comprehensive oversight, per the Federal Food, Drug, and Cosmetic Act, covers all these aspects, making 'all of the above' the full answer.
