Answer : Option C
Explanation :
The World's largest bio-fuel plant has been established with a production capacity of 100 million liters per year, is located in Brazil. Brazil is commonly referred to as having the world's first "sustainable biofuels economy," which is a misnomer given that the country has never relied on ethanol to supply more than about 18% of its total energy requirements, though a 50% by volume peak was reached in the mid 1990s. As bio-diversity is pretty high in tropical Brazil, hence the raw material for bio-fuel is easily available.
