The answer is:
All three would accurately describe this situation
How to get the solution
The radio tower encodes information into the radio wave signal: True. The radio tower encodes information (such as music or audio content) into the radio wave signal it transmits. This encoding allows the information to be carried by the electromagnetic waves.
A listener will need a radio to decode the signal and listen to the music: True. A radio receiver is necessary for a listener to receive the transmitted signal, decode the information carried by the radio waves, and convert it back into music or audio that can be heard.
Information is encoded into the radio wave by modulating the radio wave: True. Modulation is the process of impressing the information (music in this case) onto the radio wave carrier signal, altering the characteristics of the wave to encode the information.
Question
