Correct Answer:

SFO

Explanation:

Understanding how airports are identified helps you pick the right code. IATA codes are the three-letter identifiers used by airlines, tickets, and baggage systems. San Francisco International Airport uses the code SFO, which is the one you’ll see on boarding passes and in flight schedules. KSFO is the ICAO code for the same airport—four letters used by pilots and air-traffic control. The other codes refer to different airports: DXB is Dubai International, SIN is Singapore Changi. So the correct IATA code for San Francisco International Airport is SFO.
