Option: 1

All the five 4\mathrm{d} orbitals have shapes similar to the respective 3\mathrm{d} orbitals.
 


Option: 2

In an atom, all the five 3\mathrm{d} orbitals are equal in energy in free state.
 


Option: 3

The shapes of \mathrm{d_{x y}\: d_{yz}\: \: and \: d_{z x}} orbitals are similar to each other; and \mathrm{d_{x^{2}}-y^{2}\: and \: d_{2}2}  are similar to each other.
 


Option: 4

All the five \mathrm{5 d} orbitals are different in size when compared to the respective \mathrm{ 4d} orbitals.

The shapes of d-orbitals are given as

As evident from the orbital diagrams, the shapes of \mathrm{dx^{2}-y^{2}} and \mathrm{dz^{2}} are not similar.

Thus, Statement in option (3) is not correct

Hence answer is option (3).
