Concerning governor speed-droop, what statement is true?

Correct Answer: Option B — If speed droop is permanent, the prime mover's final speed is different for each amount of loading.

Permanent speed droop is a governor characteristic where the steady-state speed of the prime mover decreases as the load increases. This allows for stable load sharing between multiple units operating in parallel, as each unit settles at a unique speed corresponding to its specific load percentage.
