What is the full form of ICAO?

The full form of ICAO is the International Civil Aviation Organization. This organization is a specialized agency of the United Nations that was established to manage and regulate international air travel and aviation safety. Its primary purpose is to create global standards for the safety, security, efficiency, and environmental protection of civil aviation. ICAO plays a crucial role in the development of international air law and policies related to aviation.

The other options do not reflect the correct name or the established role of the organization. For instance, the first option mistakenly uses "Aeronautics" instead of "Aviation," which is not the correct terminology in the context of the organization. The third option provides a fictitious name, as there is no such council specifically called the International Council of Aviation Officers. Lastly, the fourth option describes an organization that does not exist, as there is no "International Convention of Aviation Operations." Understanding the correct name and function of ICAO is essential for grasping the framework of international aviation safety and regulations.
