💡 Solution & Explanation

Entropy is a state function, so for any cyclic process, $\Delta S_{\text{sys}} = 0$. This makes Statement II correct. However, for an *irreversible* cycle, the total entropy of the universe must strictly increase ($\Delta S_{\text{univ}} > 0$). Since $\Delta S_{\text{univ}} = \Delta S_{\text{sys}} + \Delta S_{\text{surr}}$, it means $\Delta S_{\text{surr}}$ must be greater than zero, rendering Statement I incorrect.
