question: Q:A 4-year-old girl is brought to the pediatrician's office by her parents with a complaint of foul-smelling discharge from one side of her nose for the past 2 weeks. There is no history of trauma to the nose and she was completely fine during her well-child visit last month. She was born at 39 weeks gestation via spontaneous vaginal delivery. She is up to date on all vaccines and is meeting all developmental milestones. Her vital signs are within normal limits. Examination of the nose reveals a mucoid discharge oozing out from the left nostril. The girl panics when the physician tries to use a nasal speculum. Palpation over the facial bones does not reveal any tenderness. An X-ray image of the paranasal sinuses shows no abnormality. Which of the following is the most likely cause of this condition?? 
  {'A': 'Nasal foreign body', 'B': 'Bilateral maxillary sinusitis', 'C': 'Nasal polyp', 'D': 'Septal hematoma', 'E': 'Nasal tumor'},
