• C. 0900, 1500, 2100, 0300

Answer: (A)

Four times a day means a dose roughly every six hours, spread evenly within a 24-hour period, while also avoiding waking the patient if possible. The times 8:00, 12:00, 16:00, and 20:00 do just that: they provide four administrations across the day with consistent spacing and keep dosing during waking hours, which helps maintain steady drug levels and supports better adherence. Other schedules either place a dose in the middle of the night or use irregular intervals, which can disrupt sleep or create uneven drug levels.
