The correct answer is: A. 1500 m and 600 m
ICAO (International Civil Aviation Organization) is an agency of the United Nations responsible for standardizing international aviation regulations. The ICAO Annex 14, Aerodrome Design, specifies the minimum runway length for different types of aircraft and airports.
The minimum basic runway length for an A type airport is 1500 m. An A type airport is an airport that can accommodate large aircraft, such as Boeing 747s and Airbus A380s.
The minimum basic runway length for an E type airport is 600 m. An E type airport is a small airport that can accommodate small aircraft, such as turboprops and light jets.
The other options are incorrect because they do not correspond to the minimum basic runway length for A and E type airports as specified by ICAO.
