The wire having a red plastic covering is a

Options

A. live wire
B. neutral wire
C. earth wire
D. none of these

Explanation

To determine the type of wire that has a red plastic covering, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Color Coding of Wires**:
- In electrical wiring, different colors are used to indicate the function of the wire. Common colors include red, green, black, and blue.

2. **Understand the Function of the Red Wire**:
- The red wire is typically used as a live wire. This means it carries current from the power source to the load (like an appliance).

3. **Differentiate Between Wire Types**:
- The live wire (often red) is responsible for carrying current.
- The neutral wire (often black or blue) completes the circuit by returning current to the power source.
- The earth wire (often green or yellow) is a safety wire that prevents electric shock by directing excess current to the ground.

4. **Conclusion**:
- Since the wire in question has a red plastic covering, we can conclude that it is a live wire.

### Final Answer:
The wire having a red plastic covering is a **live wire**.
