Which of the following is the best example of a form of kinetic energy being transformed into a form of potential energy?

• During photosynthesis, plants use light from the sun to build sugar molecules.

• During combustion, fuel, such as wood or oil, is broken down chemically to produce heat and light.

• In a generator, an armature spinning in a magnetic field produces electric current.

• In a battery, a chemical reaction releases electrons that can flow as electric current.
