Examination shows dry mucous membranes. Abdominal and rectal examinations are unremarkable. Laboratory studies show: Hematocrit 46% Leukocyte Count 6,500/mm3 Platelet Count 220,000/mm3 Serum Na+ 136 mEq/L K+ 3.2 mEq/L Cl- 102 mEq/L HCO3- 33 mEq/L Mg2+ 3.3 mEq/L Urea nitrogen 14 mg/dL Creatinine 0.8 mg/dL Abdominal ultrasound shows no abnormalities. Colonoscopy shows dark colored mucosa with interspersed white spots. Biopsies of colonic mucosa are obtained and sent for pathological evaluation. Which of the following is the most likely underlying cause of this patient's symptoms?"   (A) Celiac disease   (B) Carcinoid tumor   (C) VIPoma   (D) Medication abuse
