\( \mathrm{KMnO}_{4} \) on treatment with conc. \( \mathrm{H}_{2} \mathrm{SO}_{4} \) forms a compound \( (\mathrm{X}) \) which decomposes explosively on heating forming \( (\mathrm{Y}) \). The \( (\mathrm{X}) \) and \( (\mathrm{Y}) \) are respectively
(1) \( \mathrm{Mn}_{2} \mathrm{O}_{7}, \mathrm{MnO}_{2} \)
(2) \( \mathrm{Mn}_{2} \mathrm{O}, \mathrm{Mn}_{2} \mathrm{O}_{3} \)
(3) \( \mathrm{MnSO}_{4}, \mathrm{Mn}_{2} \mathrm{O}_{3} \)
(4) \( \mathrm{Mn}_{2} \mathrm{O}_{3}, \mathrm{MnO}_{2} \)
