Answer:
3rd law of thermodynamics
Explanation:
According to the third law of thermodynamics, at absolute zero the entropy of a system is constant or the entropy is equal to zero. The randomness in a system is referred to as its entropy.
\(S_{T=0}=0\)
When the temperature on the Kelvin scale is equal to zero, it is called an absolute zero condition.
Hence, the correct option is (c) " the third law of thermodynamics ".
