Domestic electrical wiring has three wires

Options

A. positive, negatie and neutrual
B. positive, negative and earth
C. live, neutral and earth
D. positive, negative and live

Explanation

**Step-by-Step Solution:**

1. **Understanding the Wiring System**: In domestic electrical wiring, there are typically three types of wires: Live (or Phase), Neutral, and Earth. Each wire has a specific function in the electrical system.

2. **Identifying the Live Wire**: The Live wire is responsible for carrying the current from the power supply to the load (the device that uses electricity). It is usually colored red or brown.

3. **Identifying the Neutral Wire**: The Neutral wire completes the circuit by carrying the unused current back to the power supply. It is typically colored blue or black.

4. **Identifying the Earth Wire**: The Earth wire is a safety feature that provides a path for fault current to flow to the ground, preventing electric shock. It is usually colored green or yellow-green.

5. **Evaluating the Options**: The question likely provides several options regarding the types of wires. Based on the understanding of the wiring system:
- Positive and negative terminals are not applicable in this context, as they pertain to DC circuits (like batteries).
- The correct identification of the wires in domestic wiring is Live, Neutral, and Earth.

6. **Selecting the Correct Answer**: From the options provided, the one that correctly identifies the three wires as Live, Neutral, and Earth is the correct choice.

**Final Answer**: The three wires in domestic electrical wiring are Live, Neutral, and Earth.
