Which classification requires specific clearance to enter?

Which classification requires specific clearance to enter?

• A. Class Alpha
• B. Class Echo
• C. Class Bravo
• D. Class Golf

Answer: (C)

In airspace, some areas are strictly controlled and require explicit authorization to enter. The airspace around busy airports is a primary example: you may not penetrate it without ATC clearance, and you must be in two‑way radio communication with ATC, ready to follow instructions and be assigned a specific transponder code and altitude. This is why the appropriate choice is the one associated with that strict entry requirement—the Bravo airspace. Echo is Class E, which you can enter without prior clearance as long as you follow ATC instructions when given. Golf is Class G, uncontrolled, so no clearance is needed to enter. Alpha is Class A, which also requires clearance, but it’s IFR-focused and entry conditions differ from the explicit clearance requirement used in Bravo.
