Rearrangement of carbocation

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?

Acid catalysed hydration of alkene give alcohol. In thic reaction addition of water takes place according to Markownikov's rule. Since intermediate carbocation is formed in this reaction, rearrangment of carbocation takes place. In oxymercuration-demercuration reaction hydration of alkene takes place according to markownikov's rule. Oxymercuratio-demercuration-dermercuration no rearrangement is possible. in hydroboration-oxidation hydration of alkene takes place according to anti marjownikow's addition. in HBO reaction rearrangement is not possible. both in oxymercuration-demercuation and hydroboration-oxidation, intermediate carbocation are not formed. Q. The product formed in the following reaction is: Pruduct
