Correct answer: D — Palatal masticatory mucosa
The palatal masticatory mucosa (hard palate) is the primary donor site for free gingival grafts and connective tissue grafts. The area between the palatal rugae and the vibrating line provides keratinised mucosa of adequate thickness. The premolar/first molar region is preferred (avoiding the greater palatine artery posteriorly and the incisive neurovascular bundle anteriorly). The graft is placed at the recipient site to augment keratinised tissue width.
