What are the three levels of classified information?

The three levels of classified information are Confidential, Secret, and Top Secret. This classification structure is used by the U.S. government to protect sensitive information from unauthorized access.

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

This classification system helps ensure that sensitive information is properly handled and accessed only by individuals with appropriate clearances, thereby maintaining national security and protecting against espionage and leaks. The other options provided do not accurately reflect the established levels of classified information recognized in government protocols.
