What is the primary source of biofuels in developing countries?

• A. Coal
• B. Wood
• C. Natural gas
• D. Solar energy

Answer: (B)

Biomass fuels come from living or recently living matter, and in developing countries the most accessible form of biomass is wood, used as firewood and charcoal for cooking and heating. This makes wood the primary biofuel there, because it’s often abundant, affordable, and practical for rural households that lack access to modern cooking fuels. Other options like coal and natural gas are fossil fuels, not biofuels, and solar energy is not a biofuel either. So wood stands out as the main biofuel source in many developing regions.
