Question

The lanthanide contraction is responsible for the fact that: (A) Zr and Zn have the same oxidation state (B) Zr and Hf have about the same radius (C) Zr and Nb have similar oxidation state (D) Zr and Y have about the same radius

Lanthanide contraction, cancels almost exacdy the normal size increase on descending a group of transition elements, thus Nb and Ta and, Zr and Hf have same covalent and ionic radii.
