Correct choice is (b) Enthalpy

For explanation: Enthalpy is the heat content in a system per unit mass. Its unit is J/kg in the SI system. It is a thermodynamic property that is governed by the state of the system and it is expressed as H=U+PV, where H is the enthalpy, U is internal energy, and P is pressure and V is volume.
