Correct answer: C — Its non-homogeneous red-white phenotype is associated with increased transformation risk, particularly when epithelial dysplasia is present

A is correct. Speckled leukoplakia is a non-homogeneous leukoplakia with red and white components. Non-homogeneous morphology is independently associated with substantially greater malignant transformation risk than homogeneous leukoplakia, while epithelial dysplasia provides additional prognostic risk. The red component should therefore increase suspicion and guide representative biopsy, although clinical appearance alone cannot prove dysplasia. High-risk HPV is not the defining cause, and these lesions can occur in non-smokers. Candida may colonise some oral white lesions but is neither necessary nor sufficient for erythroleukoplakia. Larger lesion size is an independent adverse feature, but speckled leukoplakia is not necessarily larger than a homogeneous lesion.
