B.

D.

Explanation:
The elements in this model are:

Encode: To translate thoughts or ideas into a form of language that can be understood by the receiver; eg, written English, spoken French or a drawn diagram.
Message: What is sent: the output of encoding
Medium: The method used for sending the message (face-to-face, telephone, email)
Noise: Something that interferes with the sending or understanding of the message (distance, culture, language differences)
Decode: The translation of the message by the receiver from the medium into their thoughts.

A single communication is complete once the feedback-message has been decoded by the sender and checked for accuracy against the original idea. Once this loop has been closed both people have a common understanding of the idea. This does not require agreement or concurrence, but if there is to be a disagreement, it helps if everyone has the same basic understanding of the issue or idea in dispute.

Effective communication requires both the sender and the receiver to be engaged.
