Solution

The correct option is B
Keto group on reacting with peroxy acid, it get oxidised to ester compound.
In this reaction, the oxygen from peroxy acid is getting inserted between the ketone and the R group.
This reaction is called Baeyer- Villiger oxidation.

One of the substituents on ketone (either $R_{1}$ or $R_{2}$ depending on the migration ability) migrates to the oxygen of the peroxide group while a carboxylic acid leaves, as shown in the above mechanism.

The order of migratory aptitude in Baeyer villiger oxidation is
$H > 3^{o} > 2^{o} > P h > 1^{o} > C H_{3}$

Thus, secondary alkyl group is migrated to form product (b).
