Answer: (C)

The equipment grounding conductor terminal screw on a receptacle or switch is required to be green. This color designation is standardized to help ensure safety and consistency in electrical wiring. The green color indicates that this terminal is specifically intended for grounding purposes, which is crucial for the safe operation of electrical devices. Proper grounding helps prevent electric shocks and ensures that electrical currents are safely diverted to the ground in case of a fault. By adhering to this color coding, electricians and technicians can easily identify grounding conductors, promoting safer installation practices and reducing the risk of accidents related to improper wiring.
