Which of the following statements is most consistent with the second law of thermodynamics as it applies to an isolated system?
(a) The entropy of an isolated system always increases, even for reversible processes.
(b) The entropy of an isolated system can remain constant only if every process occurring within the system is reversible.
(c) The entropy of an isolated system increases only when heat is added to the system from the surroundings.
(d) The entropy of an isolated system remains constant as long as no heat crosses the boundary, regardless of reversibility.
