Vedclass · Answer

(D) $Fe$ (Iron) exhibits more than one oxidation state (commonly $+2$ and $+3$) because it is a transition metal belonging to the $d$-block elements. Transition metals have partially filled $d$-orbitals,allowing them to lose electrons from both $ns$ and $(n-1)d$ orbitals,resulting in variable oxidation states.
