Verified by Toppr

The correct option is D They show different multiple state always differ by multiple of two
Transition elements can have different oxidation states. Most of the elements show variable oxidation states. The reason being when transition metals form compounds, the electrons present in ns and (n-1)d orbitals can participate in bonding due to almost similar energies.
