What are three main components of communication?

The correct answer is (C) Sender, Message, Receiver.

• Communication is a dynamic and continuous process that fundamentally requires three core structural elements to establish a basic communication loop: a source who encodes and initiates the information (Sender), the actual content or information being transmitted (Message), and the destination who decodes and interprets the information (Receiver).
• In the communication model, the process initiates at the sender, flows through the transmission of a well-defined message via a chosen medium or channel, and terminates or elicits a response at the receiver's end, thereby forming the indispensable triad of interpersonal and transactional communication systems.
• Option (A) includes 'Touch' which is a specific tactile channel rather than a structural component; Option (B) includes 'Money' which is irrelevant to general communication theory; and Option (D) includes 'Postman' which represents a secondary transmission medium rather than a primary systemic component. Therefore, Option (C) is the only universally accepted fundamental triad.
