Explanation
Answer: C - The mandible and maxilla is formed from intramembranous ossification. Intramembranous ossification begins in connective tissue membranes where osteoprogenitor cells differentiate into osteoblasts. The osteoblasts create a collagen matrix that ossifies and forms the maxilla and mandible.
