Destroying classified information so that it can't be recognized or reconstructed.

• A. Destruction
• B. Declassification
• C. Erasure
• D. Sanitization

Answer: (A)

When disposing of classified information, the key is irreversible disposal that prevents any possibility of recognition or reconstruction. Destruction achieves this by physically destroying the media or material so the contents cannot be read, reassembled, or recovered, even with forensic methods. Declassification is about changing the classification status, not disposing of information. Erasure or sanitization target removing digital data to prevent recovery, but they’re typically about making data unrecoverable within the media and may not fully address the irreversible, whole-media destruction required for items that could be reconstructed or identified if not completely destroyed. Therefore, the term that best fits the description is destruction.
