Correct answer
Bs, px, py, dx2 - y2
Step-by-step explanation
Hybridization of square planar complex is dsp2 .
In square planar complex all 4 surrounding atoms and central atom are in the same plane and let this plane is x y plane. As it is dsp2 hybridized, so it has 1 d orbital, 1 s orbital and 2 p orbital.
s orbital is non-directional, so we just write it as s.
In px the two lobes are along x-axis and in py two lobes are along y-axis
One d orbital is dx2 y2, it means out of four lobes of d orbital two along x-axis and two along y-axis.
