Identify the incorrect statement from the following. (1) All the five $5d$ orbitals are different in size when compared to the respective $4d$ orbitals. (2) All the five $4d$ orbitals have shapes similar to the respective $3d$ orbitals. (3) In an atom, all the five $3d$ orbitals are equal in energy in free state. The shapes of $d_{xy}$, $d_{yz}$ and $d_{zx}$ orbitals are similar to each other; and $d_{x^2-y^2}$ and $d_{z^2}$ are similar to each other.
