$C$. for either intermolecular redox reaction or displacement reaction.

(C) In the reaction $2NaI + 2H_2SO_4 \,(Conc.) \longrightarrow Na_2SO_4 + I_2 + SO_2 + 2H_2O$:$1$. The oxidation state of $I$ changes from $-1$ in $NaI$ to $0$ in $I_2$ (oxidation).$2$. The oxidation state of $S$ changes from $+6$ in $H_2SO_4$ to $+4$ in $SO_2$ (reduction).$3$. Since two different elements ($I$ and $S$) undergo oxidation and reduction in the same reaction,it is an intermolecular redox reaction.$4$. Therefore,the correct classification is $C$.
