Solution
The correct option is B Radio
Cellphone and radio works the same way. Cellphone can be said as a two way radio as both the sender and receiver can send audio signals simultaneously while in radio only audio signals are sent one way from sender to receiver .The way mobile works is same as radio .The audio waves goes to the mic where they are converted to electric signals,then they are carried to receiver's device by modulation and then again the receiver's device converts the electric signals to the audio output.
