Final Answer:
A communication delivered through speech or signals is known as a "Message." Option B is the answer.
Step-by-step explanation:
In the context of communication, a "Message" is the content or information conveyed through various means, including speech and signals.
Option 2 correctly identifies the term for the communication itself. Language (Option 1) refers to the system of words or symbols used for communication.
Signals (Option 3) are the non-verbal or auditory cues used to transmit information.
While "Conversation" (Option 4) typically involves an exchange of messages between two or more participants, it specifically denotes a more interactive and dialogic form of communication.
Therefore, "Message" is the most fitting term for communication delivered through speech or signals.
Option B is the answer.
