Which statement about drills is true?

Explanation:
Drill sizes follow an inverse relationship between the size label and the actual diameter: higher numbers mean smaller diameters. So as you move from #1 to #80, the drill becomes progressively smaller. That’s why the statement about numerical drills is true. The other statements don’t hold as a universal rule. The idea that letter drills change size in a straightforward increasing or decreasing way across the entire alphabet isn’t guaranteed in standard drill sets, so it isn’t a reliable general rule.
