Which set of times represents a true four-times-a-day (QID) dosing schedule?

Explanation:
The key idea is that a true four-times-a-day (QID) dosing schedule means dosing roughly every six hours, four times within a 24-hour period. In the set of times starting at 0600, the gaps are exactly six hours: 0600→1200 is 6 hours, 1200→1800 is 6 hours, and 1800→0000 is 6 hours. That clean, consistent six-hour spacing across the day is what defines a true QID pattern. The other options don’t fit as neatly. The sequence starting at 0800 has four-hour gaps (every four hours), so it’s not QID. The remaining schedules also show six-hour spacing, but they wrap around midnight differently and can be less straightforward to implement as a single daily pattern. The 0600–1200–1800–0000 sequence clearly demonstrates the intended six-hour interval, making it the best representation of QID.
