Noise management in educational communication – UGC NET Question

Statements A, B, C and E are correct, whereas D is incorrect. A is true because reducing unnecessary sound and movement minimises physical noise. B is true since repeating or visually emphasising key points provides backup when part of the message is lost. C is true as questioning helps the teacher diagnose whether learners have missed something. E is true because using more than one channel creates alternative pathways for meaning. D is false because teachers can influence psychological noise by building interest, reducing anxiety and creating a supportive climate. Therefore, D only is the wrong statement.

Option A:
Option A treats both A and D as wrong, but A correctly describes a practical strategy for reducing physical noise. Including A among wrong statements contradicts common classroom management practice, so A and D only cannot be accepted.

Option B:
Option B labels C and D as wrong, yet C accurately points out that checking understanding reveals the effects of noise. Misclassifying C undermines the diagnostic role of questioning, making C and D only an invalid option.

Option C:
Option C correctly identifies D only as the incorrect statement. It acknowledges that psychological noise is not entirely beyond teacher influence and that the other statements present valid strategies for managing different types of noise. Thus, D only is the correct answer.

Option D:
Option D lists B, C and D as wrong, but both B and C describe sound strategies for dealing with noise. Including them with D in a set of supposed wrong statements results in a logically inconsistent combination, so B, C and D only cannot be accepted.
