Step-by-step explanation:

An echo is a natural phenomenon when sound reflects back to the listener with a delay after the actual sound time. When we shout and then we could hear the same sound back, that is called the echo. So it doesn't come without one making a sound. So it is only a reply and can not initiate sound production first.
