For diatomic molecules, the correct statement(s) about the molecular orbitals formed by the overlap of two 2pz orbitals is(are)
(A) σ orbital has a total of two nodal planes
(B) σ* orbital has one node in the xz-plane containing the molecular axis.
(C) π orbital has one node in the plane which is perpendicular to the molecular axis and goes through the center of the molecule.
(D) π* orbital has one node in the xy-plane containing the molecular axis.
