Q. Which has maximum number of equivalents per mole of the oxidant?

$I^{-} (a q) + I O_{3}^{-} (a q) \to I_{3}^{-} (a q)$

$A g (s) + N O_{3}^{-} (a q) \to N O_{2} (g) + A g^{+} (a q)$

$M g (s) + V O_{4}^{3 -} (a q) \to M g^{2 +} (a q) + V^{2 +} (a q)$

$Z n (s) + V O^{2 +} + (a q) \to V^{3 +} (a q) + Z n^{2 +} (a q)$
