Whenever they operate using General class frequency privileges✓الإجابة الصحيحة
Whenever they operate on any amateur frequency
Whenever they operate using Technician frequency privileges
A special identifier is not required if their General class license application has been filed with the FCC

The AG indicator exists to tell listeners that you are transmitting on privileges the FCC database does not yet show. It is required exactly when you are exercising those upgraded privileges, and not on frequencies your Technician license already covers.
