Best answer
Correct option is (a) Distance covered by a direct space wave from transmitting to receiving antenna

Easy explanation: LOS (Line of sight) is defined for space wave propagation. It is the distance covered by a direct space wave from transmitting to receiving antenna. It depends on the height of the transmitting and receiving antennas and effective earth’s radius factor k.
