What security clearance levels are recognized in government agencies?

The government recognizes three specific security clearance levels: Confidential, Secret, and Top Secret. Each level denotes a specific sensitivity of information and the potential impact that unauthorized disclosure could have on national security.

Confidential clearance is the lowest level, granting access to information that could cause damage to national security if disclosed. Secret clearance allows access to information that could cause serious damage, and Top Secret clearance provides access to the most sensitive information that, if disclosed, could cause exceptionally grave damage to national security.

This classification system ensures that individuals only access the information necessary for their duties, aligning access to the sensitivity of the data involved. The other choices do not correspond to established government clearance terms and levels, reflecting either incorrect terminology or arbitrary categorizations that do not align with the standardized system used by federal agencies.
