Assertion (A): Electric appliance with metal body has three electrical connections. But an electrical bulb has two electrical connection.
Reason (R ): Three pin connection reduces chances of electrical shocks.

Options

A. Both A and R are true and R is the correct explanation of A
B. Both A and R are true but R is NOT the correct explanation of A
C. A is true but R is false
D. A is false and R is true

Explanation

To solve the assertion and reason question, we will analyze both the assertion (A) and the reason (R) step by step.

### Step-by-Step Solution:

1. **Understanding the Assertion (A)**:
- The assertion states that electric appliances with a metal body have three electrical connections, while an electric bulb has only two connections.
- **Analysis**: This is true. Appliances like refrigerators or irons have three pins in their plugs: live, neutral, and ground. In contrast, an electric bulb typically only has two connections: live and neutral.

2. **Understanding the Reason (R)**:
- The reason states that a three-pin connection reduces the chances of electrical shocks.
- **Analysis**: This is also true. The third pin (ground) in a three-pin plug provides a path for any leakage current to safely flow to the ground, preventing the user from receiving an electric shock.

3. **Connecting Assertion and Reason**:
- We need to determine if the reason correctly explains the assertion.
- The assertion explains the presence of a ground wire in metal-bodied appliances and the absence of it in electric bulbs. The reason explains the safety function of the ground wire.
- Since the ground wire is specifically there to prevent electric shocks in appliances with metal bodies, the reason does indeed explain why these appliances have three connections while electric bulbs do not.

4. **Conclusion**:
- Both the assertion and the reason are true, and the reason correctly explains the assertion.
- Therefore, the correct answer is that both A and R are true, and R is the correct explanation of A.

### Final Answer:
Both Assertion (A) and Reason (R) are true, and R is the correct explanation of A.
