    option A I has most rotation Barrier because it has purely double bond. while in case of II and III there is resonance so no purely double bond there are some single bond characters. More the resonance more is the single bond characters in double bond so less rotation barrier. III has more resonance than II so more single bond characters and hence least rotation barrier
