Assertion: Biodiesel is made from raw materials such as vegetable oils, animal fats, etc. Reason: Biodiesel reduces the particulate emissions from unburnt carbon.
Explanation
Option (B) is correct. The Assertion is true because the text explicitly states that biodiesel is made from raw materials such as animal fats, vegetable oils, etc. The Reason is also true as the text confirms that biodiesel reduces the particulate emissions from unburnt carbon. However, the Reason is not the correct explanation of the Assertion because the Reason highlights an environmental advantage of biodiesel, whereas the Assertion describes the source materials used in its production.
Solution Steps
Step 1: Verify the Assertion. The text lists 'animal fats, vegetable oils' as raw materials for biodiesel. Thus, the Assertion is True.
Step 2: Verify the Reason. The text states biodiesel 'reduces the particulate emissions from unburnt carbon'. Thus, the Reason is True.
Step 3: Analyze the relationship. The Reason explains a benefit/property of the fuel, not why it is made from specific raw materials. Thus, the Reason is not the correct explanation for the Assertion.
