Use your knowledge of alkene chemistry to predict a product even though you have never seen this reaction before
Choose the correct answer from the options given below:
| Column $I$ | Column $II$ |
| $(A)$ $\mathrm{O}_2^{-} \rightarrow \mathrm{O}_2+\mathrm{O}_2{ }^{2-}$ | $(p)$ redox reaction |
| $(B)$ $\mathrm{CrO}_4{ }^{2-}+\mathrm{H}^{+} \rightarrow$ | $(q)$ one of the products has trigonal planar structure |
| $(C)$ $\mathrm{MnO}_4^{-}+\mathrm{NO}_2^{-}+\mathrm{H}^{+} \rightarrow$ | $(r)$ dimeric bridged tetrahedral metal ion |
| $(D)$ $\mathrm{NO}_3^{-}+\mathrm{H}_2 \mathrm{SO}_4+\mathrm{Fe}^{2+} \rightarrow$ | $(s)$ disproportionation |
