B. Both Assertion and Reason are correct, but Reason is not the correct explanation of Assertion.
C. Assertion is correct, but Reason is incorrect
D. Assertion is incorrect, but Reason is correct

Answer

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

### Step-by-Step Solution:

1. **Understanding the Assertion (A)**:
- The assertion states that "In these days, the world is looking for better non-conventional energy sources."
- This implies that there is a global shift towards exploring and utilizing energy sources that are not based on fossil fuels.

2. **Understanding the Reason (R)**:
- The reason states that "Due to the increase in pollution caused by conventional energy resources, developing countries are looking for new energy sources."
- This indicates that the pollution from conventional energy sources (like coal, oil, and natural gas) is prompting a search for alternatives, especially in developing nations.

3. **Evaluating the Relationship**:
- The assertion is about the current trend towards non-conventional energy sources.
- The reason provides a justification for this trend, linking it to pollution issues caused by conventional energy sources.
- Both statements are true and the reason explains why the assertion is valid.

4. **Conclusion**:
- Since both the assertion and reason are true, and the reason correctly explains the assertion, the correct choice is that both the assertion and reason are true, and the reason is the correct explanation of the assertion.

### Final Answer:
The correct option is (1): Both assertion and reason are true, and the reason is the correct explanation of the assertion.
