Options

  1. ACoke
  2. BPropane
  3. CPetrol
  4. DWax

Correct answer

B. Propane

Step-by-step solution

Clean fuel, is a Natural fuel, like compressed natural gas or liquefied petroleum gas, or a blend like gasohol. It produces less pollution than the alternatives and it is used as a substitute for fossil fuels. Examples of clean fuels include most types of ethanol, biodiesel, natural gas, biogas, electricity, propane and hydrogen.
