Correct answer: A — Congenital syphilis

Hutchinson incisors (tapered, peg-shaped or screwdriver-shaped permanent upper central incisors with a central notch on the incisal edge) and mulberry molars (Moon molars — first permanent molars with hypoplastic, lobulated occlusal surfaces resembling a mulberry) are pathognomonic of congenital syphilis (Treponema pallidum transmitted transplacentally). Along with interstitial keratitis and eighth nerve deafness, Hutchinson teeth are part of the Hutchinson triad. These dental defects result from spirochetal infection during tooth development.
