None of the above

Explanation:
Detailed explanation-1: -Electrophilic addition reactions usually occur in alkenes.
Detailed explanation-2: -In an addition reaction an alkene adds elements to each of the carbons involved in the -bond, resulting in formation of sp3 carbons from sp2 carbons. This is one of the most important types of reactions that alkenes undergo. Another important type of reaction involving alkenes is oxidative cleavage.
Detailed explanation-3: -A majority of these reactions are exothermic, due to the fact that the C-C pi-bond is relatively weak (ca. 63 kcal/mole) relative to the sigma-bonds formed to the atoms or groups of the reagent.
