Final answer:
Green is not a common color for a receptacle terminal; it is used for the grounding screw. Black, silver, and brass are used for hot, neutral, and hot terminals respectively.
Step-by-step explanation:
The color not commonly associated with a receptacle terminal is B. Green. In electrical engineering, when wiring receptacles, the color coding of the terminal screws is important to ensure proper connectivity: Black (or red in some cases) indicates the hot wire, silver screws are for the neutral wire, and brass screws are for the hot terminal. The green screw, on the other hand, is universally recognized as the grounding terminal, not a receptacle terminal where you would connect the black or white wires of a circuit.
