(C) $Na_2O_2$ is a strong oxidizing agent. It oxidizes $SO_3^{2-}$ to $SO_4^{2-}$.Given the reaction: $Na_2SO_3(aq.) + Na_2O_2(aq.) \to Na_2SO_4(aq.) + Na_2O(aq.)$.Here,$X = Na_2SO_3$ and $Y = Na_2SO_4$.When $Y$ $(Na_2SO_4)$ reacts with $BaCl_2$,it forms $BaSO_4$ $(Z)$,which is a white precipitate insoluble in dilute $HCl$.Therefore,the anion present in salt $X$ is $SO_3^{2-}$.
