Which code maps to the 737-400 (code 734)?

• A. 737-400
• B. 738
• C. Crj
• D. 734

Answer: (D)

Aircraft codes are shorthand mappings that link a specific aircraft type to a dedicated numeric code for quick reference. For the 737-400, the assigned code is 734, so that code maps to this model. The other options don’t fit because they point to either a different item (the aircraft name written as a code) or a different aircraft entirely: 738 would correspond to a different 737 variant, and Crj denotes a different jet family altogether.
