The order of MO energies in B2, C2, and N2 (2p > 2p), is different from the order in O2, F2, and Ne2 (2p > 2p). This is due to ________.
 
  A) less effective overlap of p orbitals in O2, F2, and Ne2
  B) the more metallic character of boron, carbon and nitrogen as compared to oxygen, fluorine, and neon
  C) greater 2s-2p interaction in O2, F2, and Ne2
  D) greater 2s-2p interaction in B2, C2, and N2
  E) less effective overlap of p orbitals in B2, C2, and N2
