Which component prevents door opening when the gear is up?

Explanation:
Door interlocks are safety devices that connect the door operating mechanism to the aircraft’s configuration. When the gear is up, the interlock blocks the door from being opened, keeping the cabin pressurized and preventing wind blast from forcing a door open in flight. This protection is why this component is responsible for preventing door opening in the gear-up condition. Hydraulic valves, brake pedals, and alarm horns don’t control door opening in flight; they serve hydraulic actuation, braking, and signaling functions, respectively.
