Correct answer: A — Maxillary first molar
The cusp of Carabelli is an accessory cusp found on the mesiopalatal (mesiolingual) surface of the maxillary first molar. It varies in expression from a slight groove or pit to a fully formed fifth cusp. It is a genetically determined trait more common in European populations. The maxillary second molar occasionally shows a smaller Carabelli trait but it is predominantly associated with the first molar.
