AI Explanation
The correct answer is A) Over speed trip.

This is done to prevent damage to the prime mover and other critical components. The other options are not correct: B) Speed-limiting governor is used to limit maximum speed, C) Under speed trip is used to detect low speed, and D) Over speed governor is used to maintain a set speed, but does not automatically shut down the prime mover like an over speed trip.
