Answer: A

Explanation: Though all the means of communication use the radio frequencies, the internet communication is the fastest. It involves email, voice message, video message etc. The telephone, television and radio use transmission lines for communication through radio frequencies, whereas the internet uses both wired and wireless means. Also it employs optic fibre, which uses light as the medium, since it is faster than the radio signals.
