What model engines are on the 737?

• A. PW4000
• B. Trent 700
• C. General Electric - CFM56
• D. JT9D

Answer: (C)

The 737 is powered by the CFM56 engine family. This GE/Safran collaboration has been the standard for the 737 across its generations, with specific variants fitted to different 737 versions (for example, the -3 on older 737 Classics and the -7B on the 737 Next Generation). The other engines listed belong to different families used on other aircraft or older jets, not the 737. PW4000 is associated with other widebodies, Trent 700 powers the A330, and JT9D was used on older jets like early 747s and DC-10s. So the engine model tied to the 737 is the CFM56.
