Which of the following statements are correct about the mechanism of this reaction? (i) A carbocation will be formed as an intermediate in the reaction. (ii) OH–will attach the substrate (b) from one side and Cl- will leave it simultaneously from the other side. (iii) An unstable intermediate will be formed in which OH– and Cl– will be attached by weak bonds. (iv) The reaction proceeds through an SN1 mechanism.

Option (i) and (iv) are the answers.

Because it is a tertiary halide, it undergoes the SN1 process, resulting in the formation of a carbocation as an intermediate.
