UGC NET Questions (Paper – 1)

Statements A, B, D and E correctly describe different types of noise, whereas C is wrong. A is true because external sounds can interfere with hearing the message. B is true as internal worries distract attention from the message. D is true since fatigue or illness can limit a learner’s ability to focus, and E is true because several types of noise may occur simultaneously. C is false because semantic noise occurs when there is misunderstanding of terms, not when there is complete agreement. Thus, C only is the wrong statement.

Option A:
Option A groups A and C as wrong, but A accurately defines physical noise as external disturbances. Including A among wrong statements misrepresents the concept, so A and C only cannot be accepted.

Option B:
Option B ties C and D together, but D is a correct description of physiological noise. Treating D as wrong contradicts standard classification, making C and D only an invalid set of wrong statements.

Option C:
Option C correctly selects C only, identifying semantic noise as misinterpretation rather than full agreement. It keeps A, B, D and E as true statements about other types of noise and their co-occurrence, so C only is the correct answer.

Option D:
Option D links C and E as wrong, yet E is true in acknowledging that multiple forms of noise can act at once. Misclassifying E as wrong leads to an inconsistent combination, so C and E only cannot be accepted.
