(B) Transition elements (d-block elements) have valence electrons in both the outermost $ns$ orbital and the penultimate $(n - 1)d$ orbital. Since the energy difference between the $(n - 1)d$ and $ns$ orbitals is very small,electrons from both can participate in bond formation,leading to variable oxidation states.
