Answer: (C)

In residential electrical wiring, the color black is commonly used to signify a hot wire. This distinction is crucial because hot wires carry electrical current from the power source to the load, which can include fixtures, outlets, and appliances. Understanding this color coding is vital for safety, as it indicates where electrical current is actively flowing, and care must be taken to avoid contact with these wires when the circuit is live. The identification of black as a hot wire helps electricians and homeowners recognize potential hazards and appropriately manage wiring during installation, maintenance, or troubleshooting. By adhering to these standards, professionals ensure they follow electrical codes and contribute to safe electrical systems in residential environments.
