$\Delta S_{\text{total}} = \Delta S_{\text{sys}} + \Delta S_{\text{surr}} > 0$

(A) According to the $2^{\text{nd}}$ law of thermodynamics,for any spontaneous process,the total entropy change of the universe must be positive.Mathematically,this is expressed as $\Delta S_{\text{univ}} = \Delta S_{\text{sys}} + \Delta S_{\text{surr}} > 0$.
