Earthing is provided in buildings to

Options

A. avoid electric shocks due to any leakage of electric current.
B. protect it from the danger of earthquakes
C. both (a) and (b)
D. none of these

Explanation

### Step-by-Step Solution:

1. **Understanding Earthing**: Earthing is a safety measure used in electrical systems. It connects the electrical system to the ground, which helps in preventing electric shocks.

2. **Purpose of Earthing**: The primary purpose of earthing in buildings is to provide a safe path for electric current to flow into the ground in case of a fault, such as a short circuit or leakage of current. This helps to protect individuals from electric shocks.

3. **Analyzing the Options**:
- **Option 1**: Protects from electric shock due to leakage of electric current. (This is correct)
- **Option 2**: Protects from the danger of earthquakes. (This is incorrect)
- **Option 3**: Both a and b. (This is incorrect)
- **Option 4**: None of these. (This is incorrect)

4. **Conclusion**: Based on the analysis, the correct answer is that earthing is provided in buildings to protect us from electric shocks due to leakage of electric current.

### Final Answer:
Earthing is provided in buildings to protect us from electric shocks caused by leakage of electric current.
