C Correct answer
Explanation

Bilateral condylar fracture may result in A. Marked anterior open bite and retrognathia. B. The medial pterygoid and masseter muscles exert a superior posterior pull on the distal mandibular segment causing it to telescope past the condylar segments. This telescoping result in premature contact in the posterior with rotation of the mandible around this point and anterior open bite.
