Correct answer: B — Non-keratinised stratified squamous epithelium
A radicular cyst is characteristically lined by non-keratinised stratified squamous epithelium. The lining develops through inflammation-driven proliferation of epithelial rests of Malassez in the periodontal ligament, usually in association with apical inflammation from a non-vital tooth. Keratinised epithelium is more characteristic of an odontogenic keratocyst, while reduced enamel epithelium is associated with formation of a dentigerous cyst around an unerupted crown. Respiratory-type ciliated epithelium and cuboidal cells may occasionally occur, particularly in maxillary lesions or as focal epithelial variation, but they are not the characteristic lining of a radicular cyst.
