What is the purpose of "Special Handling Markings"?

The purpose of "Special Handling Markings" is to indicate that unclassified information is restricted. These markings serve as a warning or alert that, even though the information is not classified, it still requires careful handling and access may be limited to certain individuals or groups. This ensures that sensitive information is not inadvertently released or mishandled, maintaining the structured flow of information and safeguarding it against unauthorized disclosure. Special Handling Markings add an additional layer of protection to information that, if disclosed, could still have significant implications, even if it does not meet the criteria for classification.

The other options relate to different aspects of information security and handling, but they do not accurately capture the distinct purpose of Special Handling Markings in signifying restricted access to unclassified information.
