The right answer is the loss of electrons.
In the oxidation reaction, the loss of electrons is in favor of another reagent called "oxidant".
Thus, rust (a mixture of oxides and hydroxides of iron) is the result of the oxidation of iron.
This can be, for example, the following reaction:
Fe → Fe2 + + 2e-
Fe2 + ion is the oxidized form of iron. The opposite reaction is then called a "reduction reaction".
