What are the two necessary elements of communication?

• A. Hearing Is Physical; Listening Means Actually Processing the Message
• B. Transmitting and Receiving
• C. Listening and Understanding
• D. Signaling and Receiving

Answer: (B)

In communication, two essential actions must happen: the message is transmitted from a sender and then received by a receiver. Without transmitting, there’s no message to transmit. Without receiving, even a well-sent message isn’t understood or acted upon. Together, transmitting and receiving create the actual exchange of information.

The other options mix in listening, understanding, or signaling—important aspects of how we process or convey messages—but they aren’t the two fundamental elements that guarantee an exchange. Hearing vs listening highlights a physical vs cognitive step, while signaling or understanding focus on parts of the process, not the two core actions that make communication possible: sending and receiving.
