Answer

Correct answer: c) A is correct R is incorrect

Assertion (A) is correct — both leukoplakia (white mucosal plaque) and erythroplakia (red, velvety mucosal plaque) are premalignant lesions of the oral cavity mucosa. Reason (R) is incorrect — it is actually erythroplakia, not leukoplakia, that carries the greater risk of malignant transformation (and more frequently already harbours dysplasia or early carcinoma at biopsy), making R a false statement.
