Answer:

A. The energy increases the molecular motion and the kinetic energy of the substance.

Explanation:

When a substance absorbs energy, the molecules will move faster because there will be more vibrations and collisions.

As a result of more molecular motion, the kinetic energy will increase because there is more movement.
