Models are simplified representations of complex processes that highlight key elements and relationships. Shannon–Weaver,Berlo and Schramm each propose diagrams for how communication works. Learning them helps students compare different theoretical views of the same process. Thus they are models of communication.

Option C:
Channels are media of transmission and are only one element inside these diagrams.

Option D:
Ethics concerns moral principles in communication,which is a different topic.
