The number of given orbitals which have electron density along the axis is
d$$_{xy}$$, d$$_{yz}$$, d$$_{xz}$$, d$$_z^2$$, d$$_{x^2-y^2}$$

1. d-Orbitals ($$d_{xy}, d_{yz}, d_{xz}, d_{z^2}, d_{x^2-y^2}$$):
   • Non-axial ($$d_{xy}, d_{yz}, d_{xz}$$): The electron density loops are oriented between the axes at a $$45^\circ$$ angle.
   • Axial ($$d_{z^2}, d_{x^2-y^2}$$): The electron density lies directly along the axes.
     • $$d_{x^2-y^2}$$ has lobes directly on the $$x$$ and $$y$$ axes.
     • $$d_{z^2}$$ has its main lobes directly along the $$z$$-axis.

Hence, Correct answer is 2
