The correct option is B H>3o>2o>Ph>1o>CH3
In first step of Baeyer villiger oxidation, the oxygen atom of peroxy acid attacks the carbonyl compound to form a tertrahedral intermediate. In next step, there is a migration of group attached to ketone to the oxygen atom from peroxy acid.
The order of migratory aptitude in Baeyer villiger oxidation is
H>3o>2o>Ph>1o>CH3
