Accelerating the compressor to the self sustaining speed of the engine is the function of which of the following components?

Correct Answer: Option C — Starter

The starter provides the initial rotational torque required to accelerate the compressor rotor to a speed where airflow is sufficient for stable combustion. Once the engine reaches self-sustaining speed, the starter disengages, allowing the turbine to provide the power necessary to drive the compressor and the load.
