Solution

The orbitals oriented along axis have electron density along the axis.

Orientation of $2p$ orbitals are as follows:

JEE Main 2023 Chemistry, Structure of Atom — solution figure 1

Orientation of ${d}_{{z}^{2}}&{d}_{{x}^{2}-{y}^{2}}:$

JEE Main 2023 Chemistry, Structure of Atom — solution figure 2 ,

Thus, ${p}_{x},{p}_{y},{p}_{z},{d}_{{z}^{2}}&{d}_{{x}^{2}-{y}^{2}}$ are axial orbitals.

The orbitals ${d}_{\mathrm{xy}},{d}_{\mathrm{yz}}\mathrm{and}{d}_{\mathrm{xz}}$ are oriented between the axis.
