Correct option is B
Oil-powered vehicles, such as those running on gasoline or diesel, emit various gases as a result of the combustion process. Let's analyze each gas mentioned:
Carbon monoxide (CO): This is a common emission from internal combustion engines due to incomplete combustion of fuel.
Oxygen (O₂): While some oxygen might be present in the exhaust, it is not emitted as a primary product of combustion. In fact, the engine consumes oxygen from the air during the combustion process.
Sulphur dioxide (SO₂): This gas is emitted by vehicles that burn fuel containing sulfur. It is a result of sulfur compounds in the fuel being oxidized during combustion.
Carbon dioxide (CO₂): This is a major emission from internal combustion engines as a result of complete combustion of hydrocarbons in the fuel.
Therefore, the correct answer is Oxygen.
