Correct Answer: Option B — The gas generator rotor fails to reach a preset RPM after the starting motor has been energized for a preset interval.

A false start occurs when the gas generator fails to achieve the required light-off or self-sustaining RPM within a specific time window after the starter is engaged. This safety logic prevents fuel accumulation in the combustion chamber, mitigating the risk of a hot start or subsequent internal engine damage.
