The correct timeframe for a supplier to report a transaction using the Controlled Substance Ordering System (CSOS) to the DEA is within 2 business days of filling the order. This requirement ensures that the DEA maintains accurate and timely records of controlled substances transactions, which is vital for monitoring controlled substances and preventing misuse. The emphasis is on a prompt reporting system to maintain compliance with federal regulations, enhancing accountability and traceability in the supply chain of controlled substances.

The choice indicating a two-month window is not aligned with the regulatory requirements intended to ensure timely reporting, thus making it an inappropriate response. Similarly, while the option of reporting within 10 days or by the end of the month may imply a level of accountability, they do not conform to the specific guidelines that mandate faster reporting. Thus, the two business days set a standard that supports both regulatory compliance and public safety.
