The correct answer is: A. International Civil Aviation Day
International Civil Aviation Day is an international observance held on 7 December each year to mark the anniversary of the signing of the Convention on International Civil Aviation by 52 countries in Chicago on 7 December 1944. The Convention established the International Civil Aviation Organization (ICAO), a specialized agency of the United Nations.
ICAO is responsible for promoting the safe and orderly development of international civil aviation throughout the world. It does this by developing international standards and recommended practices, and by providing technical assistance to its member states.
International Civil Aviation Day is an opportunity to raise awareness of the importance of aviation and to celebrate the achievements of the ICAO. It is also a time to reflect on the challenges facing aviation and to discuss how they can be addressed.
The other options are incorrect because:
- World Kindness Day is celebrated on 13 November.
- World Malaria Day is celebrated on 25 April.
- International Nurse Day is celebrated on 12 May.
