- C.mark the boundary of a stadium TFR
Correct answer
A. keep instrument approach paths within controlled airspace
Why
Class D surface extensions protect instrument approach and departure paths that reach beyond the basic radius. They are part of the controlled surface area, not drone corridors or event restrictions.
