O The bond lengths are the same because the resonance structure you drew was tetrahedral. O The bond lengths are the same because single, double, and triple bonds are always the same length. O The bond lengths are the same because structures A and B are equivalent and therefore make equal contributions to the hybrid.arrow_forward
