Answer

Brief Explanations:

In a car - engine, chemical energy in fuel first transforms into thermal energy through combustion. Then thermal energy is converted into kinetic energy to move the car. There is no direct conversion of chemical energy to gravitational potential energy in a car - engine operation, and also no direct conversion of thermal energy to electrical energy in the basic engine - powering - car process (electrical energy is mainly from the alternator which has a more complex process not directly related to the main engine energy conversion). But the most incorrect one is the conversion of chemical energy to gravitational potential energy.
