Correct answer: A). Forecasting weather
A weather radar is an instrument that is used to locate precipitation, calculate its motion and determine the type i.e hail, snow or rain. It sends electromagnetic energy pulse into the atmosphere. If that pulse of energy interacts with something, then it reflects back the energy, which can be sensed by the weather radar.
Nowadays, most radar used are Doppler effect, which has dual polarization, it determines that movement is toward or away from the radar.
Hence, the correct answer would be option A.
