World Biofuel Day observed every year on?

Correct Answer: C. 10 August

World Biofuel Day is observed every year on August 10 to spread awareness about the importance of non-fossil fuels as an alternative for humanity. The day also attempts to highlight the government’s efforts to encourage the biofuel sector. Biofuels are environment-friendly fuels that can be produced using biological materials like agricultural waste, trees, crops or even grass. Biofuels can be produced in a very short time and stored in either liquid or gaseous form. In contrast to fossil fuels, biofuels are renewable, sustainable and biodegradable in nature.
