The answer to this question is option C which is third law.
It is because the third law of thermodynamics gives information about the definite entropy of a substance.
It states that the entropy of a substance approaches the constant value when the temperature level approaches zero.
With an exception of the non-crystalline solids, the entropy of a substance at absolute zero is close to zero.
