Which organization administers the global maritime distress system?

The correct choice is the International Maritime Organization (IMO) because it is the specialized agency of the United Nations responsible for regulating shipping and ensuring maritime safety. The IMO oversees the establishment of the Global Maritime Distress and Safety System (GMDSS), which is an international communication system that enhances the safety of ships and their crews in distress situations.

Through the GMDSS, vessels are equipped with standardized equipment that allows for rapid and effective communication in case of emergencies, thus significantly improving response times and coordination during maritime distress events. The IMO develops and updates the regulations and guidelines governing these systems, ensuring that they adapt to new technologies and safety standards.

The other organizations mentioned do not hold the same authority or specific responsibility for the global maritime distress system.
