Solution

The correct option is B $3 d_{z^{2}}$
The five d-orbitals are $d_{x y}, d_{y z}, d_{z x}, d_{x^{2} - y^{2}}, d_{Z^{2}}$
and have shapes as given in the figure. It is clear that $d_{Z^{2}}$ -orbital has one lobe along z-axis and donut-shaped electron cloud perpendicular to it in xy plane, while all other d-orbitals have two dumbells eiher along the axis ( $d_{x^{2} - y^{2}}$ ) or in between the axis ( $d_{x y}, d_{y z}, d_{z x}$ )
