Explanation:

The publication that provides detailed regulations, guidance, and procedures for classifying, marking, handling, and safeguarding classified information, as well as for access to and disclosure of this information, is the Code of Federal Regulations (CFR). The CFR includes a massive set of rules published annually, where federal agencies post their rules, including those on quality systems, manufacturing practices, and clinical practices. It is structured to help users navigate the volume of information it contains. The Freedom of Information Act (FOIA), on the other hand, is a primary legal example of sunshine laws and requires the executive branch of the U.S. government to provide information requested by citizens. The FOIA also outlines nine exemptions where information, such as that concerning national security or foreign policy, might be withheld.
