• B

  The difference in energy of the resonance hybrid and the least stable contributing structures (having highest energy) is called resonance energy. 

• C

  The difference in the experimental and calculated enthalpies (bond enthalpy, formation or combustion or hydrogenation) is called resonance energy. 

• D
