The second law of thermodynamics states that for a spontaneous process, the entropy of the universe always increases. This means that the total entropy change, which is the sum of the entropy change of the system and its surroundings, must be greater than zero. This is represented by option D. The other options are incorrect as they are either not necessarily true or are in contradiction with the second law.
