Which action does 14 USC 89 NOT explicitly authorize Coast Guard officers to perform?

The correct choice identifies an action that 14 USC 89 does not explicitly authorize Coast Guard officers to perform. While 14 USC 89 grants the Coast Guard the authority to conduct searches, inquiries, and make arrests, it does not provide specific authority to make referrals to other agencies.

The focus of 14 USC 89 is primarily on the enforcement of laws and regulations at sea, including the ability to stop, board, and search vessels, which aligns with the actions listed in the other choices. These powers are fundamental to maintaining safety and enforcing maritime laws. However, making referrals to other agencies is more of an administrative or procedural action that may occur as a result of findings from the Coast Guard's authorized actions but is not explicitly covered under this section of law. Therefore, it stands out as the action that lacks direct authorization within this statute.
