Correct answer: D — The physiological diastema mesial to the maxillary primary canine and distal to the mandibular primary canine
Primate spaces (anthropoid spaces) are physiological diastemata (spaces) in the primary dentition that occur mesial to the maxillary primary canines and distal to the mandibular primary canines. They are named after the similar spacing pattern seen in non-human primates. These spaces are developmentally normal and facilitate the mesial shift of the first permanent molars into Class I occlusion during the transition from primary to permanent dentition. Their presence is a positive prognostic indicator for adequate arch space.
