Refer to Figure 20. What class of airspace surrounds Norfolk International (ORF), shown by the concentric solid magenta rings labeled with altitudes such as 40/SFC and 40/12?

Choices

✓ Class Ccorrect
Solid magenta concentric rings with a surface area and a shelf (e.g., 40/SFC inner, 40/12 outer) depict Class C airspace — as the excerpt also labels "NORFOLK CLASS C."
Class B
Class B is depicted with solid blue rings, not magenta.
Class D
Class D is a single dashed blue segmented circle, not concentric solid magenta rings.
Class E surface area
A Class E surface area is a dashed magenta line, not the solid magenta rings shown.

Why

Solid magenta rings — a surface core plus a shelf, annotated with ceiling/floor altitudes in hundreds of feet — indicate Class C airspace. The excerpt confirms it with the "NORFOLK CLASS C" label.
