For the redox reaction $${MnO_{4}}^{-}+{C_{2}O_{4}}^{2-}+H^{+} \rightarrow {Mn}^{2+}+CO_{2}+H_{2}O $$ the correct coefficients of the reactants for the balanced equation are

A

$$MnO_{4}^{-} - 5, C_2O_{4}^{2-} - 16, H^{+} - 2$$

B

$$MnO_{4}^{-} - 2, C_2O_{4}^{2-} - 16, H^{+} - 5$$

C

$$MnO_{4}^{-} - 2, C_2O_{4}^{2-} - 5, H^{+} - 16$$

D

$$MnO_{4}^{-} - 16, C_2O_{4}^{2-} - 5, H^{+} - 2$$
