The requirement for reviewing classified information for declassification is at least every five years, making this the correct answer. This regulation ensures that classified information is reevaluated periodically to determine if it still meets the criteria for classification. By conducting these reviews, agencies can identify information that may no longer require protection, thus promoting transparency while ensuring that sensitive information is adequately safeguarded.

Reviewing classified information every five years allows for a systematic approach to its management, helping to balance the need for security with the principles of openness in government. This timeframe is established by regulations that emphasize the importance of regular reassessment, considering both the relevance and potential risks associated with the information in question.

While some may assume that classified information should be reviewed more frequently, such as annually or every three years, the five-year interval is sufficient to maintain security protocols while facilitating informed decisions about the potential declassification of information. Additionally, waiting longer than five years, such as ten years, could lead to an unnecessary backlog of outdated classifications, impeding progress toward greater transparency.
