Correct answer: C — Keratinised stratified squamous epithelium
The attached gingiva and hard palate are covered by keratinised (or parakeratinised) stratified squamous epithelium, providing mechanical protection during mastication. The sulcular epithelium and junctional epithelium are non-keratinised. The buccal mucosa, floor of mouth, and ventral tongue are also non-keratinised. Understanding keratinisation patterns is important for identifying mucosal lesions and planning flap surgery.
