Step-by-step solution

The given reaction is an example of dehydration of alcohol. In this reaction the first step is protonation of alcohol which leads to the formation of carbocation. The carbocation formed undergo rearrangement to get stability. The tertiary carbocation formed in this reaction involved in ring closure, which loses proton to from alkene. The steps are shown below.
