question: Q:A 37-year-old-man presents to the clinic for a 2-month follow-up. He is relatively healthy except for a 5-year history of hypertension. He is currently on lisinopril, amlodipine, and hydrochlorothiazide. The patient has no concerns and denies headaches, weight changes, fever, chest pain, palpitations, vision changes, or abdominal pain. His temperature is 98.9°F (37.2°C), blood pressure is 157/108 mmHg, pulse is 87/min, respirations are 15/min, and oxygen saturation is 98% on room air. Laboratory testing demonstrates elevated plasma aldosterone concentration and low renin concentration. What is the most likely explanation for this patient’s presentation?? 
  {'A': 'Aldosterone-producing adenoma', 'B': 'Ectopic secretion of anti-diuretic hormone (ADH)', 'C': 'Increased activity of the epithelial sodium channel at the kidney', 'D': 'Mutation of the Na-K-2C- cotransporter at the thick ascending limb', 'E': 'Renin-secreting tumor'},
