Remember:
Basicity is alwas first check by the hybridization of the Nitrogen atom group.
Basicity increases in the following order:
sp3 > sp2 > sp.
Therfore I AND IV options have N atom sp3 hybridized.
And during Resonance also take care that the lone pair of atoms if taking part in Resonance should not consdered for the hybridization.
