(B) The activation energy $\Delta G^{\ddagger}$ is inversely related to the stability of the transition state,which is closely related to the stability of the intermediate carbocation formed during the electrophilic addition of $HBr$ to an alkene.More substituted alkenes generally form more stable carbocations,which lowers the activation energy of the rate-determining step.Comparing the given alkenes:$A$: $3,4$-dimethylpent-$1$-ene (monosubstituted alkene)$B$: $2,3$-dimethylpent-$2$-ene (tetrasubstituted alkene)$C$: $3,4$-dimethylpent-$2$-ene (disubstituted alkene)$D$: $2,3$-dimethylbut-$1$-ene (disubstituted alkene)$2,3$-dimethylpent-$2$-ene is the most substituted alkene among the choices,and its protonation leads to a highly stable tertiary carbocation. Therefore,it has the lowest activation energy $\Delta G^{\ddagger}$.

Which reaction has the lowest $\Delta G^{\ddagger}$ (Activation Energy)?
