What does ICAO stand for?

The correct answer is known as the International Civil Aviation Organization. ICAO is a specialized agency of the United Nations that is responsible for coordinating and regulating international air travel. Its primary focus is to ensure safe and orderly growth of international civil aviation around the world. This involves setting standards and regulations for aviation safety, security, efficiency, and environmental protection.

The organization's work is crucial in developing global aviation policies and conducting audits to check compliance with international standards. By establishing these guidelines, ICAO aims to enhance safety and reliability in international air transportation.

The other options do not accurately represent ICAO’s mission or breadth of activities. They either misinterpret the organization’s name or its role, which does not align with the recognized and established definition of ICAO.
