Sabrina Daniel · Answer 1

If a substance absorbs energy that means its molecular motion will increase as well. It is kind of equivalent of adding heat to some substance which will make its molecules move faster.

Because of molecules moving faster that means that kinetic energy of molecules will increase as well because kinetic energy is energy of motion.

The answer is first option.
