A) This is true because of the principle of conservation of energy, which states that energy can neither be created or destroyed, but it can be interchanged from one form to another. 
B) The energy that was stored in the gasoline as chemical potential energy was released in the process of combustion and converted to heat energy and mechanical energy of the moving car.
