Final answer:
The green/bare wire in 120V wires represents the ground wire, which provides a safe path for the current and helps protect against electrical faults.
The Correct Option is; 1) Ground wire
Step-by-step explanation:
The green/bare wire in 120V wires represents the ground wire.
This wire is connected to the earth to provide a low-resistance path directly to the ground. It helps protect against electrical faults and provides a safe route for the current to flow in case of a short circuit.
The ground wire is often colored green or is left bare to easily identify it.
