Given below are two statements - one labelled Assertion (A) and the other Reason (R). In the light of the above statements, choose the correct option:

Motivational aspects of learning and communication efficacy are in fact closely interrelated, so the Assertion that they are unrelated is incorrect.

Communication is a social product and does carry its own variables within a learning environment, so the Reason is correct.

A motivated learner attends, encodes and responds better, which directly raises the effectiveness of classroom communication.

The Reason names sender, receiver, message, channel and feedback as variables that operate in any social act of communication.

Communication effectiveness rises and falls with the learner's motivation, confirming the interdependence that the Assertion wrongly denies.

Berlo's SMCR model, source, message, channel and receiver, formalizes these communication variables.
