On treating a compound with warm dil. $H_{2}SO_{4}$,gas $X$ is evolved which turns $K_{2}Cr_{2}O_{7}$ paper acidified with dil. $H_{2}SO_{4}$ to a green compound $Y$. $X$ and $Y$ respectively are
- A$X = SO_{2}, Y = Cr_{2}O_{3}$
- B$X = SO_{3}, Y = Cr_{2}O_{3}$
- C$X = SO_{2}, Y = Cr_{2}(SO_{4})_{3}$
- D$X = SO_{3}, Y = Cr_{2}(SO_{4})_{3}$
