Enhance secretion of conjugated bilirubin and induce bilirubin conjugation by UDP Glucuronyltransferare, B. Induce bilirubin conjugation by UDP Glucuronyltransferare and competitive inhibition of hemeoxygenase, C. Induce bilirubin conjugation by UDP Glucuronyltransferare and enhance secretion of conjugated bilirubin, D. Competitive inhibition of hemeomygenase and enhance secretion of conjugated bilirubin', 'role': 'user'}, {'content': 'Answer: B \nExplanation: Phenobarbitone:\nIt induces UDP Glucuromyltransferase\n↓\nIncrease Bilirubin conjugation\nMetalloporphyrins:\nIt is competitive inhibitor of hence oxygenase, which converts hence to bilirubin.', 'role': 'assistant'}]
