The question is incomplete. The image showing the compound and the options in the questions is attached.
Answer:
B
Step-by-step explanation:
If we closely examine the structure of the compound given in the question, we will notice that the reaction must involve the substitution of the hydroxyl group by chlorine in the parent molecule.
This occurs when the -OH group combines with H^+ to form -OH2^+ which is a good leaving group.
Compound B is formed because, when -OH2^+ leaves, a carbocation is created. This carbocation is stabilized by the alkyl groups attached to the carbon atom bearing the leaving group by +I inductive effect. This carbon atom bearing the leaving group is a tertiary carbon atom thus it forms a more stable carbocation. Hence the product formed.
