The correct sequence of stages for a jet engine is characterized by intake, compression, combustion, and exhaust. Initially, air enters the engine through the intake stage, where it is guided into the engine. In the compression stage, this incoming air is compressed by fans or compressor blades, which increases its pressure and temperature to optimize the efficiency of the combustion process.

The combustion stage follows, wherein fuel is injected into the high-pressure, high-temperature air and ignited. This combustion generates a high-energy flow of hot gases. Finally, the exhaust stage occurs when these gases are expelled out of the engine through the nozzle, producing thrust according to Newton's third law of motion.

This sequence reflects the fundamental operation of a jet engine and aligns with basic aerodynamics principles, making it crucial for understanding jet propulsion mechanics. The other options do not accurately represent the accepted terminology or progression of a jet engine's operation, highlighting the significance of the correct choice in understanding jet engine functionality.
