  2. Kinetic

  3. Potential

  4. Heat

Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

 chemical energy is the potential of a chemical substance to undergo a transformation through a chemical reaction to transform other chemical substances.

kinetic energy is due to motion.
potential energy is due to relative position.
heat energy is due to temperature.
in petrol different different reaction occurs which provide energy to run the engine, so energy possessed in petrol is chemical energy.
option A.
