1.	The lanthanide contraction is responsible for the fact thatA. `Zr` and `Y` have about the same radiusB. `Zr` and `Nb` have similar oxidation stateC. `Zr` and `Hf` have about the same radiusD. `Zr` and `Ce` have the same oxidation state.
Answer» Correct Answer - C Due to poor shielding of `(n-2)` f-electrons, size of `Zr` and `Hf` remain same.
