AMain propulsion reduction gear.
BTurbo-generator reduction gear.
CMain engine turning gear.
DAuxiliary power take-off gear.
AI Explanation
The correct answer is C) Main engine turning gear. A worm gear drive is commonly used in the main engine turning gear on ships. The turning gear is used to slowly rotate the main propulsion engine when the ship is in port, allowing the engine to be turned over without starting it. This prevents distortion of the engine components from sitting idle for long periods. The worm gear drive provides a high reduction ratio to enable the slow, controlled rotation of the large main engine. The other answer choices do not typically utilize worm gear drives for their applications.
