In communication process, to encode mean to

In the communication model (Shannon-Weaver and its successors), encoding is the sender's step of translating an idea into a form that can travel through a channel, such as words, gestures, symbols or electrical signals. Decoding is the reverse, where the receiver turns the signal back into meaning. Option B is the closest match, though its wording is loose: it describes the signal being produced, not the receiver's neural processing.

• A is wrong. Encoding is about expressing an existing idea clearly, not about creating something new.
• B is the best fit. Encoding converts the message into a transmittable signal.
• C is wrong. Blocking a pathway describes a communication barrier or noise, not encoding.
• D is wrong. Building morale is a motivational function. It has nothing to do with encoding.

The core concept is the sender-encoding-channel-decoding-receiver-feedback chain. For Mains, this matters in administration: a collector's circular is effective only when the message is encoded in clear, unambiguous language that the field staff can decode correctly.

Trap: aspirants confuse encoding with decoding and pick the option that sounds like 'receiving' or 'understanding'. Ask who is doing the action: encoding is always the sender's job.
