Solution

The correct option is A. Benzene
An additional conjugated double bond has resonance energy = 21 kJmol^-1. Benzene has resonance energy = 151 kJmol^-1whereas 1,3-butadiene and 1,3-cyclohexadiene have energy approx. 21 kJmol^-1and 1,3,5-hexatriene has 2 additional conjugated bonds and resonance energy= 42 kJmol^-1.
