Best answer
The correct option is (a) Tropospheric Scattering

The best I can explain: Signal scatters in forward direction above the radio horizon and it travels beyond the LOS. The signal strength is decreased as only a small amount of it is forward scattered and so high power amplifiers are equipped at the receivers.
