What must records show about drugs distributed by a distributor?

The correct answer focuses on the requirement for detailed record-keeping associated with drugs that have been distributed. Records must indicate the identity and quantity of drugs disposed of because this information is crucial for tracking the drug's journey through the supply chain, ensuring accountability, and complying with regulatory standards.

This requirement helps prevent drug diversion and misuse by maintaining a clear and accurate record of what drugs are in circulation, how much is being handled, and the lifecycle of those drugs, especially in instances of disposal. Such comprehensive records are key in audits and inspections by regulatory bodies.

In contrast, other options mention aspects that, while potentially relevant, do not fulfill the specific regulatory requirements for documentation regarding drug distribution. Knowing the name and address of the delivery person or the method of transportation does not necessarily provide sufficient detail on the drugs themselves, and expiration dates alone do not reflect the flow of drugs through the system or their disposal, which is why these would not satisfy the criteria needed for compliance.
