Correct answer: D. Points 9 and 11

In standard cephalometric analysis, the maxilla-to-mandible (sagittal jaw) relationship is classically represented by comparing the position of the maxilla (commonly via Point A) against the position of the mandible (commonly via Point B), each referenced to a common landmark like Nasion — corresponding to the labeled points marked near the upper and lower jaw in the image.
