Who is responsible for formulating, encoding, and transmitting a message?

The source is the entity that initiates the communication process by formulating, encoding, and transmitting a message. In the context of agricultural extension and communication, this can be an individual, group, or organization that has information or knowledge to share with others. The source plays a crucial role in ensuring that the message is clearly articulated and effectively conveyed to the intended audience.

The process involves encoding the information into a format that can be understood by the receiver, which includes selecting appropriate language, symbols, or mediums. Once the message is prepared, it is transmitted through appropriate channels, making it essential for the source to be well-informed and skilled in communication techniques.

In this situation, the other options represent different components of the communication process. The receiver refers to the individual or group intended to receive the message, while the transmitter is often a medium or tool through which the communication flows, such as a phone or television. An extension worker typically serves as the facilitator or intermediary in the process but is not the originator of the content itself.
