Rusting of iron, basically is an electrochemical reaction. In this process -

Options

A. `Fe^(2+)(aq) and O_(2)` are formed due to the oxidation of `Fe` and `H_(2)O(l)` respectively
B. reduction of `Fe^(2+)` leads of the formation of `Fe(s)` and reduction of `O_(2)(g)` in presenceo of and `H^(+)(aq)` leads to the formation of `H_(2)O(l)`
C. oxidation of Fe leads to the formation of `Fe^(2+)(aq)` ion and reduction of `O_(2)` in presence of `H^(+)(aq)` leads to the formation of `H_(2)O(l)`
D. oxidation of Fe leads to the formation of `Fe^(3+)(aq)` ion and reduction of `H_(2)O(l)` leads to the formation of `O^(2-)(aq)`

Answer

C
