According to 14 USC 2, what responsibility does the Coast Guard have?

The responsibility of the Coast Guard as outlined in 14 USC 2 is to enforce applicable federal laws in specific jurisdictions. This encompasses a wide range of activities, including ensuring compliance with maritime laws, protecting navigational safety, preventing drug smuggling, and promoting national security on the waters.

This provision enables the Coast Guard to operate not only in federal waters but also in other jurisdictions where federal law applies, thereby giving it the authority to take action when necessary to uphold the rule of law in maritime environments.

While the other options present different roles that could be associated with maritime operations or federal enforcement, they do not precisely encapsulate the broader mission defined by 14 USC 2. The Coast Guard's primary focus is not limited to inspecting all vessels, managing recreational activities, or guarding land borders, but rather it is about enforcing laws across a spectrum of maritime issues, which includes safety and security measures integral to the functions of the Coast Guard.
