Assertion : Charcoal does not produce a flame.
Reason : Charcoal does not vaporise.

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

To analyze the assertion and reason provided in the question, we can break it down step by step.

### Step-by-Step Solution:

1. **Understanding the Assertion**:
- The assertion states that "Charcoal does not produce a flame."
- This means that when charcoal is burned, it does not create a visible flame like other combustible materials (e.g., wood or paper).

2. **Understanding the Reason**:
- The reason given is "Charcoal does not vaporize."
- This implies that during the burning process, charcoal does not turn into gas (vapor) which is necessary for producing a flame.

3. **Analyzing the Relationship**:
- To produce a flame, a substance must vaporize when it burns. The vaporized material ignites and creates a flame.
- Since charcoal does not vaporize, it cannot produce a flame when it burns.

4. **Conclusion**:
- Both the assertion and the reason are correct. The assertion that charcoal does not produce a flame is true, and the reason that it does not vaporize is also true.
- Furthermore, the reason correctly explains why the assertion is true.

5. **Final Answer**:
- Therefore, the correct option is: "Both Assertion and Reason are True and Reason is the correct explanation for Assertion."
