C) Natural gas
D) Petroleum

Answer 1

Hint: These are basic kinds of questions that can be solved if you remember the secondary fuel concept or the secondary fuel properties.

Complete step by step answer:

Secondary fuels are fuels, which are produced through chemical or physical processes from some primary fuel or fuels. These are fuels that are not discovered as natural resources. These fuels are also generated to enhance the capacity of combustion to bring energy into a motor. That implies secondary fuels are also a type of intermediate energy between primary energy and energy services. Such an intermediate form is also classified as an energy currency but also requires electricity that is not a fuel. So the example of secondary fuel is water gas.

Note: You’re going to think here because you know what is secondary fuel but what is water gas so that it is explained as water gas is a poisonous flammable gaseous mixture consisting mainly of carbon monoxide and hydrogen with small quantities of methane, carbon dioxide, and nitrogen, generally made by blowing air and then steaming over red-hot coke or coal and used as a fuel or as carburetor.
