IMO stands for International Maritime Organization, the United Nations specialized agency responsible for maritime safety, security, and environmental protection in shipping. It standardizes rules and conventions for ships, crews, and ports, helping to keep sea travel and international trade safe and orderly. The organization is best known for frameworks like SOLAS and MARPOL, which set important global standards. The other options don’t fit because they refer to different fields or do not exist as major international bodies: for example, the meteorological body is the World Meteorological Organization, not the maritime one, and there is no internationally recognized organization called International Monetary Organization or International Missionary Organization.
