The incorrect statement regarding molecular orbital(s) is 

The $\sigma$ bonding molecular orbital does not contain nodal planes containing the inter nuclear axis.   

If a nodal plane lies in the inter nuclear axis then corresponding orbitals is $Pi\left(\pi \right)$ bonding M.O.

If there is a nodal plane perpendicular to the inter nuclear axis and lying between the nuclei of bonded atoms then corresponding orbital is anti bonding M.O.

The $\delta -$ bonding molecular orbital possess three nodal planes containing the inter nuclear axis.
