Who is authorized to receive and handle classified national security information?

The option stating that anyone with a clearance is authorized to receive and handle classified national security information is correct because access to such information is strictly regulated and requires individuals to have the appropriate security clearance that matches the level of classification. This includes various personnel across different sectors, not just limited to military members or government employees. Individuals may include contractors, civilian employees, and even military personnel, provided they have the requisite clearance.

Having a security clearance signifies that the individual has undergone thorough vetting and background checks to ensure they can be trusted with sensitive information. The security clearance process assesses an individual's loyalty, reliability, and integrity, which are critical traits when handling classified data. This system allows for a diverse array of personnel—both in government and contracted roles—to work effectively in environments that require access to classified national security information, thereby optimizing organizational security efforts.

The other options are limited and do not reflect the reality of how access to classified information is structured. For instance, not only military personnel or government employees are involved; that's why those answers do not encompass the full scope of who can be authorized to handle classified material.
