D: Fibrous dysplasia
Answer: D: Fibrous dysplasia 
Explanation: Fibrous dysplasia- 
The normal radiolucent maxillary sinus may be partially or totally replaced by the increased radiopacity of  this lesion. The degree of radiopacity depends on its stage of development and the relative amounts of bone and fibrous tissue present. Usually the radiopaque areas have a uniform characteristic ground-glass appearance on extraoral images or an orange-peel appearance on intraoral views. Onion-peel appearance is not seen in this condition.
