Statement (I) :  Nitrogen has higher IP1 than oxygenstatement (II) :Outer E.C of VA group is ns2 np3 (half filled) where as VI A group is ns2 np4

In general, in a period ,IP1  increase from left to right.∴IP1 of 'N' must be lesser than IP1 of 'O'.but due to stable configuration (ns2np3), IP1 of 'N' is higher than expected.∴IP1 of 'N' > IP1 of 'O'
