Answer
- D Almost in a straight line like light (quasi-optical)
Explanation
VHF waves propagate almost like light. Mountains, buildings and the curvature of the Earth block them. The higher you fly, the greater the range. At low altitude a radio may no longer reach a ground station that is out of line of sight.
