In the following molecular orbital formation, which of the following option is incorrect?

 

The incorrect statement is “Its molecular orbital has 2 nodal plane”.

Due to the fact that  $\pi \ast 2py$ is an antibonding molecular orbital, which is created when two p orbitals destructively overlap, $\pi \ast 2py$ has two nodal planes. One node is created when the destructive overlap takes place, and there is already another node in the p orbital. ${\pi }_{p-d}\left(u\right)$ has only 1 nodal plane. Hence correct option is D.
