In the process of communication the first step is.

The standard communication model runs: sender, then encoding, then message, then channel, then receiver, then decoding, then feedback. Once the sender has an idea, the first operational step is to convert it into symbols such as words, gestures or images. That conversion is encoding, so option A is correct.

• Message (B): This is the product of encoding, not the step that produces it. It exists only after encoding is done.
• Decoding (C): The receiver interprets the message. It comes near the end of the chain, after transmission.
• Receiving (D): This happens only after the message has travelled through the channel, so it cannot be first.

The core concept is the linear sender-to-receiver model that Shannon-Weaver and later communication theorists built on. For Mains, the same model helps in answering GS2 questions on citizen charters and government outreach, where a message fails if it is poorly encoded for its audience.

Trap: Aspirants pick "Message" because it is the thing being sent first. The message is what encoding produces, so the process step comes before it.
