b major
The supertonic triad in the key of A flat major is B flat, D flat, and F natural
The dominant is the 5th, which in the key of A-flat major is E-flat. Then an E-flat major triad contains the notes E-flat, G, and B-flat.
D-flat, F, A-flat for the triad
The tonic note of any diatonic scale is the first note (starting note) of the scale. In the case of G-flat major the tonic note is G-flat!
Each scale has a Leading Tone (which is the 7th note of the scale) and a Tonic Note (which is the first/eighth note of the scale). For the key of C major, the leading tone would be B, and the tonic note would be C.
