Columbia, South Carolina is represented by which airport code?

Columbia, South Carolina is represented by the airport code CAE, which stands for Columbia Metropolitan Airport. This code is derived from the airport's name, following the common practice where airport codes are often similar to the city or airport name for easier identification by travelers and airlines. The code CAE specifically helps in distinguishing Columbia's airport from other nearby airports and ensures accurate routing for flights. The use of CAE for Columbia aligns with the conventions of three-letter airport codes used by organizations like the International Air Transport Association (IATA).

Other options represent different airports entirely, which is why they are not correct in this context.
