Which statement about mailing classified information is correct?

• A. Top Secret may be mailed via USPS express mail
• B. Secret information may be mailed via USPS registered mail
• C. Confidential information may be mailed via USPS registered mail
• D. All levels may be mailed via USPS with no restrictions

Answer: (B)

Mailing classified information requires choices that preserve confidentiality and provide a verifiable trail of custody during transit. Registered Mail adds extra security by giving documented custody at each handling step, along with tracking and insurance, making it suitable for Secret information. The other options imply either using high-speed USPS services for Top Secret material or allowing all levels to be mailed without restrictions, which conflicts with the need for stricter controls on classified material. Therefore, the statement that Secret information may be mailed via USPS registered mail best reflects the safer, controlled approach.
