Step 1: Understanding the Concept:
Communication systems are classified based on timing and interaction dynamics.
When people exchange messages, the timing of the interaction determines whether it is real-time or delayed.
Step 2: Detailed Explanation:
Let us analyze the communication terms listed:
1. Symbolic communication:
This refers to using shared symbols, gestures, or signs to convey meaning.
It describes the medium of communication rather than the timing of the interaction.
Thus, Option (A) is incorrect.
2. Symptomatic communication:
This is a physiological or behavioral expression of a underlying physical or psychological condition.
It is not defined by mutual, real-time exchange.
Thus, Option (B) is incorrect.
3. Synchronous communication:
This describes communication that occurs in real-time, where all parties participate and respond simultaneously.
Examples include face-to-face conversations, telephone calls, and live video chats.
This matches the mutual exchange of information at the same time.
4. Intrapersonal communication:
This is the internal dialogue that occurs within an individual's own mind (e.g., self-reflection or thinking).
It does not involve an exchange between different people.
Thus, Option (D) is incorrect.
Step 3: Final Answer:
Real-time, mutual communication is called synchronous communication.
This corresponds to Option (C).
