The ENERGY difference between (n-1)d and ns subshell is very less. Transition metals have (n-1)d and ns electrons. After losing some s and d electrons, transition metals can acquire immediate half-filled and fully filled stable configurations. They MAY have more than one such OXIDATION states.Since both (n-1) d and ns take PART in CHEMICAL bond formation.Option C is correct.
