The correct answer is (a) Brazil.
Brazil is the world’s largest producer and consumer of gasohol, a blend of gasoline and ethanol. In 2019, Brazil produced 31.1 billion liters of gasohol, and consumed 29.8 billion liters. The United States is the second largest producer and consumer of gasohol, with production of 14.3 billion liters in 2019 and consumption of 13.4 billion liters.
Gasohol is a renewable fuel that can be produced from sugarcane, corn, or other plant materials. It is a cleaner-burning fuel than gasoline, and it can help to reduce greenhouse gas emissions. Brazil has been a leader in the development and use of gasohol, and it is now the world’s largest producer and consumer of this fuel.
The other options are incorrect. Cuba is not a major producer or consumer of gasohol. India is a major producer of gasohol, but it is not the largest producer or consumer. The United States is the second largest producer and consumer of gasohol, but it is not the largest producer.
