In the drug scheduling system described, what is the range of schedules?

• A. Schedule I to Schedule VI
• B. Schedule II to Schedule VII
• C. Schedule I to Schedule VII
• D. Schedule III to Schedule VII

Answer: (C)

In this scheduling system, substances are placed across a sequence of levels, with the described set spanning from the first level up to the seventh. Asking for the range means identifying the full span that includes all seven levels, not just a subset. That’s why the inclusive range from the first to the seventh is the best choice—it covers every schedule described in this system. The other options omit either the earliest levels or the latest level, which is why they don’t fit the described range. (Note: in real life, some systems use fewer schedules, but this question uses seven as the described range.)
