Which of the following statements best describes the meaning of the phrase "entropy is a state function"?
(a) Because entropy depends on the path only when a process is irreversible, it is not truly a state function in those cases.
(b) Entropy change equals the total heat added divided by the absolute temperature, no matter how the process occurs.
(c) The change in entropy of a system depends only on its initial and final equilibrium states, not on the specific path taken between them.
(d) Entropy remains constant for any adiabatic process, whether the process is reversible or irreversible.
