(D) In the electrophilic addition of $Cl_2$ to an alkene,the first step involves the formation of a cyclic halonium ion intermediate. For cyclohexene,the reaction with $Cl_2$ leads to the formation of a cyclic chloronium ion. This species is more stable than a simple open-chain carbocation because the lone pair on the chlorine atom can be donated into the empty $p$-orbital of the carbocation,effectively delocalizing the positive charge. Therefore,the cyclic chloronium ion is the most stable intermediate.

Which of the species shown below is the most stable form of the intermediate in the electrophilic addition of $Cl_2$ in water to cyclohexene to form a halohydrin?
