Clearance Issuer COMMS

The only correct answer here is DELIVERY. AFISAFIS —Aerodrome Flight Information Service is not ATC; ATISATIS —Automatic Terminal Information Service is a pre recorded broadcast, and DISPATCH is the company frequency. DEPARTURE will be monitoring your flight after departure. It is true to say that on smaller airfields GROUND (or even TOWER) might issue a clearance but DELIVERY is the correct answer here.
