Drill 1: Class B shelf
Your site (★) is between the inner and outer solid blue rings around a major airport. The segment label reads 100 over 30. What applies to a Part 107 flight at 200 ft AGL here, assuming terrain near sea level?
Answer: C. Solid blue lines are Class B. Sector altitudes are MSL with the last two zeros omitted, so '100 over 30' is a ceiling of 10,000 ft MSL and a floor of 3,000 ft MSL. At 200 ft AGL near sea level you are below that floor, so you are not in Class B. The shelf tells you nothing about the airspace beneath it: that is whatever else is charted at your site. Often it's Class G up to a Class E floor at 700 ft AGL (magenta vignette) or 1,200 ft AGL, which needs no ATC authorization. But it can also be Class C (solid magenta), Class D (dashed blue), or a Class E surface area (dashed magenta), and §107.41 requires prior ATC authorization (e.g., via LAANC or FAADroneZone) for all of those.
