Answer:
B.They will break down.
Explanation:
Entropy is defined as the thermal energy per unit temperature that contribute to doing useful work in a system. The concept of entropy says that entropy is measured by the random or disordered motion of molecules of a system.
As the entropy will increase over time, the molecules will break down into two or more due to the random and disordered motion of molecules.
Hence, the correct answer is "B.They will break down.".
