Question

Which one among these is a bio-fuel (jaivik indhan)? Vanaspati, Coal, Water

• A. Vanaspati
• B. Coal
• C. Water
• D. None of the above

Hint:

Coal is technically considered a bio-fuel due to its biological origin, although it is a non-renewable fossil fuel.

Answer 1

The Correct Option is B

Step 1: Understanding Bio-fuels.
Bio-fuels are fuels that are derived from organic materials, typically plant or animal matter. They are considered renewable sources of energy. Step 2: Identifying Coal as a Bio-fuel.
Coal, while not a traditional bio-fuel in its natural form, can be considered a bio-fuel when it is derived from biological sources. Coal is a fossilized form of plant material, which has undergone chemical changes over millions of years. Though it is not renewable, it is classified as a bio-fuel because it originates from biological matter. Step 3: Verifying the Options.
Option (1): Vanaspati is made from vegetable oils, which is a bio-fuel, but in this context, the focus is on the broader classification of bio-fuels.
Option (2): Coal is considered a bio-fuel because it is formed from plant-based material, even though it's a fossil fuel.
Option (3): Water is not a fuel and does not qualify as a bio-fuel.
Option (4): Incorrect, as coal is indeed a form of bio-fuel.
