Which of the following statements is true about email? email has entirely replaced phone and face-to-face conversations. email is a form of oral communication. email is a type of new media. email allows a communicator to reach only one person at a time. email came into existence during the 1950s.

All of them look false to me but your best bet is either Email came into existence during the 1950s. or  Email allows a communicator to reach only one person at a time. But you can email more than person at a time and email came out in the 1960s. Email is pretty old and hasnt entirely replaced face to face conversations.
