The correct answer reflects the design specifications of the H60H helicopter regarding its fire detection system. In the H60H model, there are two fire detectors installed for each engine and one for the Auxiliary Power Unit (APU). This configuration is critical for effectively monitoring temperature and detecting potential fire hazards in both engines and the APU, which are vital components during operations.

The two fire detectors per engine ensure that there are redundant systems in place, allowing for reliable detection of any abnormal temperature increase or fire. Meanwhile, having one detector for the APU is sufficient due to its operational characteristics and the typically lower risk compared to the main engines.

This well-thought-out arrangement of fire safety equipment is essential for enhancing the safety and operational readiness of the helicopter in various mission environments.
