SMCR elements in classroom communication – UGC NET Question

Statements A, B and D correctly describe the SMCR model in a classroom, while C is incorrect. A is true because the teacher who originates the instructional message functions as the source. B is true since in Berlo’s model the message includes content, elements, structure and treatment. D is true because the receiver is the learner with particular communication skills, attitudes and knowledge that influence decoding. C is false because channels in SMCR include human senses and non-electronic means, not only technological media, so the correct set of statements is A, B and D only.

Option A:
Option A includes A and B, both of which are correct, but it omits D which also correctly identifies the receiver as learners with particular characteristics. Because it fails to include all the true statements about the model, A and B only cannot be the correct answer. This option underrepresents the role of the receiver in SMCR.

Option B:
Option B brings together A, B and D, capturing the teacher as source, the rich composition of the message and the learner as receiver with specific characteristics. It also excludes C, which wrongly limits the channel to electronic media. Since it lists all and only the correct statements, this option is the accurate answer.

Option C:
Option C selects B and D only and leaves out A, thereby ignoring the explicit recognition of the teacher as source in classroom SMCR applications. Although B and D are correct, omitting A makes the combination incomplete. Hence B and D only cannot be accepted as fully correct.

Option D:
Option D treats all four statements A, B, C and D as if they were correct, but it wrongly includes C, which misinterprets the notion of channel. Because it mixes one incorrect statement with three correct ones, this option is not valid as the correct answer.
