Lewis theory of octet does not explain :

Limitation of Lewis concept to explain the cause of covalent bond formation and the nature of attractive force between the adjacent atoms in molecules.

Fails to explain the geometry of a molecule.

It could not explain the release of energy during formation of covalent bonds.

It violates octet rule the evidence is the formation of molecules where the central atom has more eight electrons in its valence shell correctly. 

Thus, the correct option is D.
