Question EASA Drone License A2 - Flight performance and planning

207 - EASA Drone A2 License - If your Visual Observer (VO) suddenly stops responding to your verbal communications during a flight, what is the safest immediate action?

Continue the mission while looking at the telemetry screen

Assume the airspace is clear and speed up

Hover the drone, safely return it to the home point, and land until communication is re-established, as you have lost your secondary safety scan

Fly the drone directly towards the VO to get their attention
