Correct answer: D — Teeth that are larger than normal
Macrodontia is an abnormality of tooth size in which one or more teeth are larger than normal. It may affect an individual tooth or multiple teeth and can occur in either the primary or permanent dentition. Teeth that are smaller than normal demonstrate microdontia, so B is incorrect. Extra roots are an abnormality of root number, while fewer cusps represent altered crown morphology; neither defines macrodontia. Absence or defective formation of enamel is an enamel-development disorder rather than an abnormality of overall tooth size.
