The correct option is A (a−r,s),(b−p,s),(c−r,s),(d−q)
(a→r,s) Enthalpy is a state function and is a function of internal energy and pressure and volume.
(b→p,s) Temperature is independent of the bulk matter of the system and hence it is an intrinsic property but it is a state variable.
(c→r,s) Free energy is a state function as it depends on the state of the system as well as it depends on H,T and S. It is also a function of U,P and V.
(d→q) Work is a path function as the amount of work done depends upon path undertaken.
