Question

Which of the following is not an example of biofuels?

• A. Obtains wood from an energy plantation
• B. Obtains petroleum from petroplantation
• C. Obtains alcohol from energy cropping
• D. Obtains natural gases from fossilization

Answer 1

The correct option is D Obtains natural gases from fossilization

Biofuels are those fuels obtained from biomass like plants, crops, etc. without geographical processes like fossilization.

Natural gases, also called fossil gas, is a naturally occurring hydrocarbon gas mixture consisting primarily of methane. It is formed when layers of decomposing plant and animal matter are exposed to intense heat and pressure under the surface of the Earth over millions of years through fossillization. Hence, option d is not an example of biofuel.
