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.
