Step-by-step explanation:
The item that is NOT part of effective communication from the list provided is D) Noise. In the context of communication, noise refers to any interference that distorts or interrupts the flow of information between the sender and receiver. The other options listed, Sender, Receiver, and Message, are fundamental components of the communication process. The sender is the person who initiates the communication by conveying a message. The receiver is the individual or group who receives the message and interprets it. And the message itself is the content or information that is being communicated. Noise, on the other hand, hinders the effectiveness of communication by causing misunderstandings and reducing the clarity of the message.
