B
c flat. the semitone above b flat is b, with is equal to c flat. So the diatonic semitone is c flat because it has to be a different note name.
C-sharp to D, or C to D-flat would be a semitone.

Tone and semitone are two words to describe differences in pitch between two notes. A semitone is the difference between F and F#, that is, only a bit. A tone is the difference between F and G, twice as much as a semitone.
A flat (♭) lowers the pitch of a note by a semitone (half-step). A sharp (#) raises the pitch of a note by a semitone. Naturals cancel out sharps or flats that apply to notes and make them their usual pitch (♮).
