A motor is protected against burnout by using an over current protection device.

Explanation:
Overcurrent protection is what keeps a motor from overheating and burning out. When a motor is overloaded or stalls, the current it draws can surge well above its safe level, causing excessive heating of the windings and insulation. An overcurrent protection device detects this excess current and trips or limits the current, cutting power before damage occurs. This protection can come from fuses, circuit breakers, or overload relays built into motor starters or drives. The other options are instruments that measure speed, not protection; they won’t prevent burnout. So the best choice is the one that describes an overcurrent protection device.
