Plastic wire is :

Options

A. An insulator
B. A conductor
C. Both (A) and (B)
D. None of these

Answer

**Step-by-Step Solution:**

1. **Understanding the Properties of Materials:**
- Materials can be classified based on their ability to conduct electricity. The two main categories are conductors and insulators.
- Conductors allow electricity to flow through them easily, while insulators do not.

2. **Identifying Plastic Wire:**
- Plastic is a type of polymer that is commonly used as insulation for electrical wires.
- It is known for its low electrical conductivity.

3. **Determining the Conductivity of Plastic:**
- Since plastic does not allow electricity to flow through it easily, it is classified as an insulator.
- This means that plastic wire does not conduct electricity effectively.

4. **Conclusion:**
- Based on the properties of plastic, we can conclude that plastic wire is an insulator.

5. **Final Answer:**
- Therefore, the correct option is: **Plastic wire is an insulator.**
