Correct answer: D — 6-12 months
The mandibular symphysis (midline fibrous joint between the two halves of the mandible) fuses between 6-12 months of age. At birth, the mandible consists of two separate halves joined at the symphysis by fibrous tissue. This fusion converts the mandible into a single continuous bone. Knowledge of this developmental timeline is important when interpreting radiographs and understanding fracture patterns in infants.
