I think the answer is C) 10mg. Based on the provided information, the oral to parenteral ratio is 7.5:1.5, so the equivalent oral dose would be 7.5 times the intravenous dose of 0.5mg, which is 3.75mg. Multiplying that by the daily dosing frequency of 6 (every 4 hours), the total daily oral dose would be 10mg.
