Identify the correct statement regarding a spontaneous process:

For a process to be spontaneous:In general, $\Delta G=\Delta H-T\Delta S<0$.For an isolated system, there is no exchange of heat or matter with surroundings. According to the Second Law of Thermodynamics, for any spontaneous process in an isolated system, the entropy of the system must increase ($\Delta S_{total}=\Delta S_{sys}>0$).Other points: Exothermic ($\Delta H<0$) and increasing entropy ($\Delta S>0$) both favor spontaneity, but neither is the sole criterion.
