State whether the following statements are true or false :
Lightning conductor cannot protect a building from lightning.

Options

A. True
B. False
C. Both A and B
D. None of these

Answer

To determine whether the statement "Lightning conductor cannot protect a building from lightning" is true or false, we can analyze the function of a lightning conductor.

### Step-by-Step Solution:

1. **Understanding the Purpose of a Lightning Conductor**:
- A lightning conductor, also known as a lightning rod, is designed to protect buildings from lightning strikes. It is typically made of conductive materials like iron or aluminum.

2. **Installation of the Lightning Conductor**:
- The lightning conductor is installed at the highest point of a building. This positioning allows it to intercept lightning strikes before they can hit the building itself.

3. **How a Lightning Conductor Works**:
- When lightning strikes, the lightning conductor provides a low-resistance path for the electrical current to follow. Instead of passing through the building, the current travels down the conductor and into the ground.

4. **Effectiveness of the Lightning Conductor**:
- By directing the lightning's electrical energy safely into the ground, the lightning conductor prevents damage to the building. This means that the building is protected from the destructive effects of lightning.

5. **Conclusion**:
- Since the lightning conductor is specifically designed to protect buildings from lightning strikes, the statement "Lightning conductor cannot protect a building from lightning" is false.

### Final Answer:
The statement is **False**. The lightning conductor is installed to protect tall buildings from lightning strikes by directing the current safely into the ground.
