What term refers to the date or event when information's national security sensitivity lapses and declassification occurs?

• A. Declassification
• B. Debriefing
• C. Data Spill
• D. Damage Assessment

Answer: (A)

Declassification is the process of removing the protection from information that was previously classified, allowing it to be released or made unclassified. The date or event when the information’s national security sensitivity lapses and this change occurs is called the declassification date or declassification event. This term directly describes both the lifting of classification and the moment it happens. Debriefing is about extracting information from people, a data spill means an unintended release of data, and damage assessment is about evaluating harm after a security incident, none of which capture the act or moment of lifting classification.
