In the given chemical reaction, colors of the Fe²⁺ and Fe³⁺ ions, are respectively :

$5{\mathrm{Fe}}^{2+}+{\mathrm{MnO}}_4^{-}+8{\mathrm{H}}^{+}\to {\mathrm{Mn}}^{2+}+4{\mathrm{H}}_2\mathrm{O}+5{\mathrm{Fe}}^{3+}$

Given data : It is given to identify  that In the given chemical reaction, colors of the Fe²⁺ and e³⁺ ions, are respectively : from the given option.

Explanation :

Depending on the number of O^2- vacancies and other point defects, iron can exist as Fe²⁺ or Fe³⁺. In corundum, Fe³⁺ and Ni³⁺ produce yellow colour, whereas Fe²⁺ produces sapphire green colour.

Hence, the correct option ( A). Green, Yellow.
