This section contains Assertion (A) and Reason (R) type questions. Each question has choices (1), (2), (3) and (4), out of which only one is correct.
Assertion (A) Fire wood is a conventional energy source.
Reason (R) Only `8-10%` energy of burning firewood is utilised and the remaining is wasted.

Options

A. Both Assertion and reason are correct, and Reason is the correct explanation of Assertion.
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 can break it down into the following steps:

### Step 1: Analyze the Assertion
- The assertion states that "Firewood is a conventional energy source."
- Firewood is indeed considered a conventional energy source as it has been used for centuries for cooking and heating.

### Step 2: Analyze the Reason
- The reason states that "Only 8-10% energy of burning firewood is utilized and the remaining is wasted."
- This statement is also correct. When firewood is burned, a significant portion of the energy is lost as heat, and only a small percentage is converted into usable energy.

### Step 3: Determine the Relationship
- While both the assertion and reason are correct, we need to evaluate if the reason provided is the correct explanation for the assertion.
- The assertion is about firewood being a conventional energy source, while the reason discusses the efficiency of energy utilization from firewood. The reason does not explain why firewood is considered a conventional energy source.

### Step 4: Conclusion
- Since both statements are correct but the reason does not correctly explain the assertion, the correct choice is that both statements are true, but the reason is not the correct explanation for the assertion.
- Therefore, the answer is Option (2): Both assertion and reason are correct, but the reason is not the correct explanation of the assertion.
