Amethod that automatically releases the door in the event of a disruption of control system power
Bspring-loaded catch that automatically lifts to release the door in the event of the presence of a fire
Cpneumatic heat sensor
Dhydraulic directional valve that automatically releases the door in the event of a disruption to the control power system
AI Explanation

The correct answer is A) method that automatically releases the door in the event of a disruption of control system power. Fire doors are designed to automatically release and close in the event of a fire or loss of power to the control system. This is a critical safety feature to prevent the spread of fire and smoke throughout a vessel. The automatic release mechanism is typically a spring-loaded latch or electromagnetic release that is triggered when the control power is disrupted, allowing the door to close under its own weight and seal off the compartment. The other options are incorrect because they do not accurately describe the automatic release mechanism for fire doors.
