Correct answer: E — A → B → D → C → E

Explanation lettering: D = shown as C · E = shown as D · C = shown as E

The typical maxillary primary tooth eruption sequence is: A (central incisor, ~10 months) → B (lateral incisor, ~11 months) → D (first molar, ~16 months) → C (canine, ~19 months) → E (second molar, ~29 months). Note that the first molar (D) erupts before the canine (C) in both maxillary and mandibular arches. The mandibular teeth generally erupt slightly before their maxillary counterparts. These are average ages with normal variation of ±6 months.
