Which term describes the mechanism where information is automatically declassified after 25 years unless exempted?

• A. Automatic Declassification
• B. A&E
• C. Atomic Energy Information
• D. Banner markings

Answer: (A)

Automatic declassification is the mechanism that releases information from classified status after a fixed period, typically 25 years, unless an exemption is applied. This built-in schedule means the clock runs automatically and materials are disclosed unless there’s a justified reason to keep them secret—such as national security or other legally defined exemptions. It balances transparency with security while reducing the need for ongoing manual reviews. The other terms don’t describe this process: one is just an acronym not tied to declassification, another refers to a category of information, and the last refers to markings on documents rather than the declassification action itself.
