Answer:
[A] All of the involved parties agree on the shared meaning of the message.
Step-by-step explanation:

Understanding in communication is only achieved when everyone agrees on the meaning of the message. If only some or part of the involved parties agree, room for misunderstanding or error is bound to happen. All parties must agree so they are all on the "same page".
