Limitations of VBT -

While the Valence Bond theory, to a larger extent, explains the formation, structures and magnetic behaviour of coordination compounds, it has some shortcomings which are listed below:
(i) It involves a number of assumptions.
(ii) It does not give quantitative interpretation of magnetic data.
(iii) It does not explain the colour exhibited by coordination compounds.
(iv) It does not give a quantitative interpretation of the thermodynamic or kinetic stabilities of coordination compounds.
(v) It does not make exact predictions regarding the tetrahedral and square planar structures of 4-coordinate complexes.
(vi) It does not distinguish between weak and strong ligands.

Therefore, option (4) is correct.
