What are the three classification levels of information?

The three classification levels of information are Confidential, Secret, and Top Secret. These levels are part of a structured system used by the U.S. government to designate information based on its sensitivity and the potential impact to national security if it is disclosed without authorization.

Confidential information is the lowest classification level, which could cause damage to national security if disclosed. Secret information is more sensitive and could cause serious damage to national security if revealed. Top Secret information is the highest classification level, and its unauthorized disclosure could cause exceptionally grave damage to national security.

This classification system is crucial for protecting sensitive governmental and military information, ensuring that access is restricted to individuals with the appropriate security clearance levels. The other options presented do not align with the established classification levels used by government agencies, reflecting either non-standard terms or a misunderstanding of the classification framework.
