Assertion : One should not use metal containers in a microwave oven
Reason : Only because metal may melt form heating.

Options

A. If both assertion and reason are true and reason is the correct explanation of assertion
B. If both assertion and reason are true but reason is not the correct explanation of assertion
C. If assertion is true but reason is false
D. If both assertion and reason are false

Explanation

**Step-by-Step Solution:**

1. **Understanding the Assertion**: The assertion states that one should not use metal containers in a microwave oven. This is a widely accepted guideline when using microwave ovens.

2. **Analyzing the Reason**: The reason provided is that metal may melt from heating. While this can be true for certain metals, it does not encompass the full range of issues associated with using metal in microwaves.

3. **Identifying the Correctness of the Assertion**: The assertion is indeed correct. Metal containers can cause problems in microwave ovens.

4. **Exploring Other Reasons**:
- Metal containers can reflect microwaves, which can lead to uneven cooking or even damage to the microwave itself.
- The risk of electric shock is also a concern, as metal is a good conductor of electricity. This can create safety hazards.

5. **Evaluating the Reason**: The reason given (that metal may melt from heating) is not the primary concern. While some metals can melt, the more significant issues are the reflection of microwaves and the risk of electric shock.

6. **Conclusion**: Therefore, the assertion is true, but the reason provided is false. The correct option is that the assertion is true, but the reason is false.
