Which of the following statements correctly describes the molecular orbitals in an O₂ (oxygen) molecule?
A) The O₂ molecule has bonding orbitals that are fully occupied and anti-bonding orbitals that are unoccupied.
B) The O₂ molecule has equal numbers of bonding and anti-bonding electrons, leading to a bond order of zero.
C) The O₂ molecule has bonding orbitals partially filled and anti-bonding orbitals fully occupied, leading to a bond order of one.
D) The O₂ molecule has bonding orbitals and anti-bonding orbitals that are both equally filled, resulting in a bond order of two.
