Each degree of freedom contributes 1 /2kbt to the energy of a system, where possible degrees of freedom are those associated with translation, rotation, and vibration of molecules. this statement refers to:
a. theorem of kinetic energy
b. theorem of equipartition of energy
c. theorem of entropy

b) Theorem of equipartition of energy

Explanation:

The equipartition theorem states that energy is shared equally amongst all energetically accessible  degrees of freedom of a system.

think of it as  another way of saying that a system will generally try to maximise its entropy by distributing the available energy evenly amongst all the accessible modes  of motion.
