Show answer and explanation
Correct answer: D. Coronoid process

- B. Ramus fractures occur at moderate frequency but less commonly than condylar or body/parasymphysis fractures.
- C. The body and parasymphysis region of the mandible are common fracture sites due to their relatively exposed position and thinner cross-section.
