Solution

The correct option is B First law
The Zeroth Law of thermodynamics- If two systems are in thermal equilibrium respectively with a third system, they must be in thermal equilibrium with each other.

First Law-Energy can neither be created nor be destroyed. It can change from one to another. The total energy of the universe remains constant.

Second Law-  In a natural thermodynamic process the sum of the entropies of the interacting thermodynamic systems increases.

Third Law-The entropy of a system approaches a constant value as the temperature approaches absolute zero.

Hence option A is the right answer.
