question: Q:A 2-day-old male infant is brought to the emergency department by ambulance after his parents noticed that he was convulsing and unresponsive. He was born at home and appeared well initially; however, within 24 hours he became increasingly irritable and lethargic. Furthermore, he stopped feeding and began to experience worsening tachypnea. This continued for about 6 hours, at which point his parents noticed the convulsions and called for an ambulance. Laboratories are obtained with the following results:
  
  Orotic acid: 9.2 mmol/mol creatinine (normal: 1.4-5.3 mmol/mol creatinine)
  Ammonia: 135 µmol/L (normal: < 50 µmol/L)
  Citrulline: 2 µmol/L (normal: 10-45 µmol/L)
  
  Which of the following treatments would most likely be beneficial to this patient?? 
  {'A': 'Aspartame avoidance', 'B': 'Benzoate administration', 'C': 'Fructose avoidance', 'D': 'Galactose avoidance', 'E': 'Uridine administration'},
