What does the echo technique ensure in communications?

The echo technique is a communication strategy used to enhance understanding and clarity between parties. When one party repeats or "echoes" the information they received, it serves to confirm that the message has been understood correctly by the recipient. This practice is especially important in emergency situations where miscommunication can lead to serious consequences. By paraphrasing or repeating the essential details of the message, operators can ensure that any critical information has been accurately conveyed and comprehended, reducing the likelihood of errors that could arise from misunderstandings.

While the other options touch on aspects of communication, they do not accurately reflect the fundamental purpose of the echo technique. It does not relate to forgetting a message, indicate that no response is needed, or ensure signal clarity. Instead, it specifically focuses on confirming comprehension between the parties involved.
