Solution

The correct option is B +1 only
Generally all these oxides the oxidation state of the alkali metal is +1. The calculation of metal oxidation state is shown below:
M2O:2x+(2)=0x=+1
(in oxide O is present as O2 )
M2O2:2x+(2)=0x=+1
(in peroxide O is present as O22 )
MO2:x1=0x=+1
(in superoxide O is present as O2
