Hm....
I thought the answer was A.
The reason why I said this was because of the external oblique ridge on the facial side of Mand 1st molar.

d. maxillary palatal

in the other situations the elastic tissue ie mucosa can accomodate for the excess tissue ( the mucogingival junction will be displaced apically in the area of the flap which is ok) while the palate has onlu keratinized non elastic mucosa, if u perform an apically displaced flap u will end up with a fold of mucosa at the base of the flap )
