Which of the following best describes the diagram below of a molecular orbital?

Based on the charges recorded in the atomic orbitals, we may determine if a molecular orbital is bonding or antibonding. Bonding occurs when the positive charge overlaps the positive charge, while antibonding occurs when the positive charge overlaps the negative charge.
It is a pi antibonding molecular orbital because, as seen in the diagram, the opposing charges overlap.
Two p orbitals laterally overlap to form pi bond.
Out of phase combination of these two p orbitals give ${\pi }^{*}\mathrm{MO}$.
Hence, the correct option is (D)
