I.$\Delta$Ssys > 0
II.$\Delta$Ssurr > 0
III.$\Delta$Suniv > 0
IV.$\Delta$Gsys > 0

The statement III, F1F1F1S1F1F1F10Suniv > 0, is always true for a spontaneous process, as a spontaneous process is one that occurs without the input of external energy and increases the entropy of the universe. Therefore, the entropy of the system and the surroundings both increase, leading to a positive change in the entropy of the universe. Statements I and IV may not always be true for a spontaneous process, as they depend on the temperature and free energy of the system. Statement II is not necessarily true, as the surroundings may not always experience an increase in entropy during a spontaneous process.
