The correct answer is A. Ethanol.
Ethanol is a renewable fuel that can be produced from plant materials such as corn, sugarcane, and switchgrass. It is a clean-burning fuel that produces fewer emissions than gasoline. Ethanol is also a domestically produced fuel, which means that it is not subject to the same price fluctuations as imported oil.
Ethene, ethylene, and ethane are all hydrocarbons. Hydrocarbons are fuels that are derived from petroleum. They are non-renewable resources and produce more emissions than ethanol.
Ethene is a gas that is used to make plastics and other chemicals. Ethylene is also a gas that is used to make plastics and other chemicals. Ethane is a gas that is used as a fuel for heating and cooking.
Ethanol is the best option for a fuel for driving vehicles because it is a renewable, clean-burning, and domestically produced fuel.
