Answer: The stage of communication is MESSAGE DECODING.
Explanation: Decoding of a message involves interpreting and understanding a message. It is the process of converting a message sent into thoughts.
A message is first received by a receiver who then begins to interpret it. The receiver translates the message into meaningful symbols that is easily understood by him. When you decode a message, you get the meaning out of a conversation or message. As such, a message can be said to be completely decoding when then is successful communication.
