The following transformation involves a carbocation rearrangement. The carbocation is generated by protonation of the hydroxyl group,followed by the loss of water. Which bond has to migrate in the carbocation to yield the product indicated (after the deprotonation)?

Given below are two statements:
Statement $(I)$: The boiling points of alcohols and phenols increase with an increase in the number of $C$ atoms.
Statement $(II)$: The boiling points of alcohols and phenols are higher in comparison to other classes of compounds such as ethers and haloalkanes.
In the light of the above statements,choose the correct answer from the options given below:
