Correct option is C
The primary purpose of running an
earth wire along the conduit is to ensure
electrical continuity between the metal conduit and metal accessories.
This is important for safety reasons, as it provides a low-resistance path to the ground (earth) in case of a fault, such as a short circuit or leakage current.
This helps prevent electric shocks by ensuring that any exposed conductive parts are properly grounded, allowing excess electricity to safely discharge into the earth.
