Explanation:

Potential energy is defined as the stored energy that an object has because of its position or shape. It is impossible to observe this energy's effects until this energy is released and transformed into some form of energy. We have two types of potential energy:

Gravitational potential energy: We can define gravitational potential energy as energy stored by a gain in height that an object makes.

Elastic potential energy: Elastic potential energy is defined as the energy stored in elastic objects (springs, rubber bands) when compressed or stretched from their natural position.

From the list of the options given: gallon of gasoline, rock sitting at the top of a cliff, sleeping dog and stopped car are all potential energy.
