The Baeyer-Villiger oxidations of the substituted diphenyl ketones proceeds as indicated because:

A. The electron-withdrawing nitro group retards the migration of the phenyl ring to which it is attached.

B. The electron-releasing methoxy group accelerates the migration of the phenyl ring to which it is attached.

C. Both A and B

D. Neither A nor B. The regiospecificity is due to steric effects in the migrating group.
