Which of the following statements is not correct w.r.t. LCAO?

${\mathrm{\psi }}_{\mathrm{MO}} = {\mathrm{\psi }}_{\mathrm{A}} \pm {\mathrm{\psi }}_{\mathrm{B}}$

Electrons in bonding molecular orbitals remain between the two nuclei most of the time there by decreasing the repulsion between nuclei

Electrons placed in bonding molecular orbitals tend to hold the nuclei together and stabilise the molecule.

The energy of bonding molecular orbital is always slightly higher than either of the atomic orbitals that have combined to form it.
