A molecule may be represented by three structures having energies \( E_{1}, E_{2} \) and \( E_{3} \), respectively. The energies of these structures follow the order \( E_{3}E_{2}E_{1} \), respectively. If the experimental bond energy of the molecule is \( E_{0} \), the resonance energy is :
(a) \( \left(E_{1}+E_{2}+E_{3}\right)-E_{0} \)
(b) \( E_{0}-E_{3} \)
\( P \)
(c) \( E_{0}-E_{1} \)
(d) \( E_{0}-E_{2} \)
