• B. COMDTINST M5501.01
• C. COMDTINST M5510.3
• D. COMDTINST M5520.01

Answer: (A)

Message classification authority and the guidelines for handling classified information are set out in this Coast Guard instruction. It defines who has the authority to classify information, the levels of classification, and the procedures for marking, transmitting, storing, and disposing of messages based on their sensitivity. This centralized policy ensures consistent application across all units and prevents mislabeling or mishandling of sensitive information. Other instructions cover different topics—one relates to publications policy and general information management, another to broader security program elements, and another to IT or cyber policy. They do not specifically codify the authority to classify messages or the handling rules for classified communications, which is why this instruction is the correct source for message classification policy.
