UGC NET Questions (Paper – 1)

Statements A, B and D are correct, whereas C is incorrect. A is true because technical issues such as poor sound and lag interfere with the transmission of messages. B is true since excessive on-screen stimuli can overload learners’ processing capacity, functioning as psychological noise. D is true as using a clear layout, limited text and simple visuals helps minimise competing signals. C is false because noise includes any interference, not just physical sound, and covers distractions, overload and technical disruptions.

Option A:
Option A lists A and B only and omits D, overlooking the role of thoughtful slide and interface design in reducing noise. Because D is also a correct statement, A and B only underrepresents strategies for dealing with online noise. Hence this option cannot be accepted.

Option B:
Option B combines A and D but leaves out B, ignoring the cognitive dimension of noise produced by overloaded screens. Excluding B means the option does not fully explain how noise can arise in online contexts. Therefore A and D only is not the correct answer.

Option C:
Option C correctly groups A, B and D and excludes C, which wrongly restricts noise to literal sound. It recognises technical, cognitive and design aspects of noise in online education. For this reason, A, B and D only is the right choice.

Option D:
Option D includes B, C and D, but C contradicts the broader conception of noise used in communication theory. Including C with accurate statements makes the combination internally inconsistent. Consequently, B, C and D only cannot be chosen.
