I would also say A.{PINNACOL PINNACOLON REARRANGEMENT) 


First H+ can create carbocation at any one of the carbon and then methyl shift(CH3-) from other carbon can occur and we would get positive charge on carbon attached directly with OH , and then OH can share its lone pair and form double bond O. So ketone on left and four degree carbon on right 


What's the answer given? 
And pls also post the efforts you had made for the question in problem description :))
