Solution

The correct option is C Energy of molecule
The valence bond theory is not perfect. It has its own sets of limitations. It fails to answer the energies of the molecules. It explains the shapes of the simple molecules and also the overlapping and hybridization of the atomic orbitals that results in the formation of chemical bonds.

In the valence bond theory, hybridization of orbitals is an integral part of the bond formation. Hybridisation consists of mixing or a linear combination of the "pure" atomic orbitals in such a way as to form new hybrid orbitals such as

s p, s p^{2}, s p^{3}, s p^{3} d, s p^{3} d^{3}
