Find the total number of feasible products (including stereoisomers) in the following reaction. (No carbocation rearrangements is observed)

Find the total number of feasible products (including stereoisomers) in the following reaction. (No carboncation rearrangements is observed)

Under common reaction conditions, a carboncation rearranges to another carbocation of equal or greater stability. For example secondary carbocation will rearrange to a tertiary carbocation. It will not rearrange to a less stable primary carbocation. This generalization is not absolute, and because there is not is a high energy barrier to the rearrangement of carbocations, rearrangement to a less stable cation can occur if it offers the chance to forme a more stable product. In which of the following cations rearrangement takes place?
