\mathrm{For \: K_2O:} 2x - 2 = 0\\\: \: \:

                        x = +1

\mathrm{For\ K_2O_2:} 2x - 2 = 0

(In peroxide, the oxidation state of oxygen is -1)
                        x = +1

\mathrm{For\ KO_2:} x - 2\times \frac{1}{2} = 0

(In superoxide, the oxidation state of oxygen is -1/2)
                      x = +1

Therefore, Option(1) is correct.
