Which of the following actions does NOT fall under the primary duties of the Coast Guard?

The primary duties of the Coast Guard focus on the enforcement of federal maritime laws, conducting safety inspections, and engaging in rescue operations, all of which are critical to ensuring safety and security on the nation's waterways. Enforcing state laws generally falls outside the purview of the Coast Guard, as this responsibility is typically managed by state or local law enforcement agencies.

The enforcement of maritime laws is directly related to the Coast Guard's mission to ensure safe navigation and security in U.S. waters. Conducting safety inspections on recreational boats is also a key duty, as it helps to prevent accidents and maintain compliance with safety regulations. Similarly, assisting in rescue operations aligns with the Coast Guard’s humanitarian mission to provide aid in emergencies. Thus, while the Coast Guard may cooperate with state agencies, it does not primarily enforce state laws, distinguishing this choice from its core responsibilities.
