Answer:
In the reaction, Fe2+ is oxidized and MnO4- is reduced (option c.)
Explanation:
MnO₄⁻ + 5Fe²⁺ + 8H⁺ ---> Mn²⁺ + 5Fe³⁺ + 4H2O
Look all, the oxidation number.
Increase the oxidation number means, oxidation.
Decrease the oxidation number means, reduction.
Fe²⁺ → Fe³⁺ is increasing, the ox. number. Fe is oxidizing.
In MnO₄⁻, the Mn acts with +7, so in Mn²⁺ has decrease the ox. number.
Mn has reducted.
