Which of the following reagents causes the aqueous colored solution of acidic $KMnO_4$ to become colorless?

What is '$A$' in the following reaction?
$2Fe^{3+} + Sn^{2+} \to 2Fe^{2+} + A$

What is the value of $x$ in order to balance the following redox reaction by the ion-electron method?
$x H_2O_2 + ClO_4^{-} \rightarrow x O_2 + ClO_2^{-} + 2 H_2O$

For the redox reaction $MnO_4^{-} + C_2O_4^{2-} + H^{+} \rightarrow Mn^{2+} + CO_2 + H_2O$,the correct coefficients of the reactants for the balanced reaction are respectively $MnO_4^{-}$,$C_2O_4^{2-}$ and $H^{+}$:
