Solution
The correct option is C 1,2,4,3
Zeroth law of thermodynamics suggests the thermal equilibrium giving the concept of temperature that two substance in contact having same temperature are in thermal equilibrium.
First law of thermodynamics is based on the conservation of energy which further gives the information about internal energy.
Second law of thermodynamics says that efficiency of an engine ca never be equal to or greater than unity.
Since internal energy is a state function, so change in internal energy is zero in a complete cyclic process as initial and final states are same.
