Among these KO2 has unpaired electrons in it !
If the number of electrons present are in even numbers then it well may be completely paired(but not sure though) but if it is odd in number then there surely are unpaired electron(s). 
Here in this case only KO2 had odd(35) electrons in it & so it clearly has unpaired ellctrons in it
