The second and third laws of thermodynamics states that absolute zero cannot be reached. The correct option among all the options that are given in the question is the third option or option "C". Both the laws actually deal with the relations that exist between heat and other forms of energy. I hope the answer helps you.

Answer:

D. the third law of thermodynamics

Explanation:

As per third law of thermodynamics we know that entropy of a perfect crystal comes to zero when the temperature of the crystal reaches to absolute zero.

So as per the theory of entropy we know that entropy of a system cannot be zero as it will reach zero then system will not exist.

So here we can say that

As per third law it is not possible to achieve zero kelvin or absolute zero temperature because at that temperature the entropy will become zero and then the system will not exist in that case.

So here we can say the correct answer will be

D. the third law of thermodynamics
