Mark what is the facial profile in malocclusion of II/I class (gnathic form).

Explanation:
In skeletal Class II malocclusion with a gnathic form, the mandible is retruded relative to the maxilla. This pulls the chin back and makes the midface seem more prominent from the side, producing a convex profile. A concave profile would be seen with a prognathic mandible (Class III), and a straight profile with well-balanced jaws. Therefore, a convex profile best matches this pattern.
