Cobalt chloride when dissolved in water forms pink colored complex X which has octahedral geometry. This solution on treating with cone HCl forms deep blue complex, Y which has a Z geometry. X , Y and Z , respectively, are

X = Co H 2 O 6 2 + , Y = CoCl 4 2 - , Z = Tetrahedral

X = Co H 2 O 6 2 + , Y = CoCl 6 3 - , Z = Octahedral

X = Co H 2 O 6 3 + , Y = CoCl 6 3 - , Z = Octahedral

X = Co H 2 O 4 Cl 2 + , Y = CoCl 4 2 - , Z = Tetrahedral

The correct statements among I to III are:
(I) Valence bond theory cannot explain the color exhibited by transition metal complexes.
(II) Valence bond theory can predict quantitatively the magnetic properties of transition metal complexes.
(III) Valence bond theory cannot distinguish ligands as weak and strong field ones.
