Answer: (B)

On the ERJ 175, the cabin door lock indicators utilize clear and green colors to convey the status of the door locks. The clear light typically indicates that the door is closed and not locked, while the green light signifies that the door is correctly closed and locked. This dual-color indicator system is essential for ensuring that the flight crew has a clear and immediate visual confirmation of the cabin door status before taxiing or during flight operations, enhancing safety protocols and operational efficiency. The use of clear and green lights helps in easily distinguishing between different door states without causing confusion.
