An ultrasound tech is trying to identify an object, but the screen of the machine is broken. Which statement best describes this situation?

• The generated sound wave will not be able to reflect off of the object.

• The sound wave will not be generated, so there will be no echoes received.

• The echoes will be made but will not be able to be received by the machine.

• The machine will not be able to process the received echoes into images.
