Best answer
The correct choice is (c) Carrier to interference ratio

The best I can explain: Meteorological information is studied to adapt the radio in accordance to the weather condition. Rain might induce carrier to interference ratio degradation, carrier to interference ratio improvement, or it might result in any change.
