The correct answer highlights the primary components involved in the operation of a gas turbine system, which are essential for its functionality. A gas turbine consists of three main parts: the compressor, combustor, and gas turbine itself.

The compressor plays a crucial role in drawing in air and compressing it to high pressure, which is vital for the combustion process. Following the compressor, the compressed air enters the combustor, where fuel is injected and ignited, resulting in a high-temperature, high-pressure gas. This gas then expands through the gas turbine, where it drives the turbine rotor and generates mechanical energy.

This configuration is fundamental to the operation of gas turbines, especially in applications for electricity generation and propulsion in aircraft. The other options contain components relevant to different systems or applications, such as a generator or heat exchanger, but do not align directly with the core structure of a gas turbine itself.
