Name the material which is bad conductor of heat and electricity.

Options

A. Non-metals
B. Metal
C. Both (A) and (B)
D. None of these

Explanation

**Step-by-Step Solution:**

1. **Understanding Conductors and Insulators**:
- Conductors are materials that allow heat and electricity to flow through them easily. Metals like copper and aluminum are good conductors.
- Insulators, on the other hand, are materials that do not conduct heat or electricity well.

2. **Identifying Bad Conductors**:
- Bad conductors are often referred to as insulators. They resist the flow of heat and electricity.

3. **Examples of Bad Conductors**:
- Common examples of materials that are bad conductors of heat and electricity include rubber, glass, wood, and plastic.

4. **Conclusion**:
- Among these, rubber is a widely recognized material that is a bad conductor of both heat and electricity.

**Final Answer**: Rubber is a material that is a bad conductor of heat and electricity.
