Answer
Please see the work below.
Work Step by Step
We know that
$N_2$ has a triple bond and a bond length is 110pm. Its geometry is linear and sp hybrid orbitals are required for one lone pair and one $\sigma$ bond.
$N_2F_2$ has a double bond and a bond length is 112pm. Its geometry is trigonal and $sp^2$ hybrid orbitals are required for one lone pair and two $\sigma$ bond.
$N_2H_4$ has a triple bond and a bond length is 145pm. Its geometry is tetrahedral and $sp^3$ hybrid orbitals are required for one lone pair and three $\sigma$ bond.
