    Correct Option - 3


    Detailed Solution:

    Mn? O? is mixed oxide which contains MnO and Mn? O? , so Mn is in +2 and +3 oxidation state respectively. Both Mn? ² & Mn³? has unpaired electrons so Mn? O? will show magnetic property. While all other oxides have no unpaired electrons either on cation or on anion.
