None', 'role': 'user'}, {'content': 'Answer: C \nExplanation: anion gap =15 (high)\nDifference in anion gap\xa0:\xa015-10= 5\nDifference in HCO3 levels\xa0: 25-10=15\n\nAs difference in HCO3 levels is more than that of anion gap , this is a case of High anion gap metabolic acidosis + compensatory respiratory alkalosis + normal anion gap metabolic alkalosis.', 'role': 'assistant'}]
