UGC NET Questions (Paper – 1)

Statements A, B and C accurately describe how virtual laboratories extend learning opportunities in science education. They allow simulated experimentation, support safety with hazardous materials and offer access to remote learners. Statement D is false because ethical and safety considerations remain important, even in virtual settings where real-world implications are discussed. Therefore the correct combination is A, B and C only.

Option A:
Option A is incorrect because it lists only A and B as correct, omitting C. While A and B are true, statement C is also correct, since virtual labs are particularly valuable where physical labs are unavailable. Excluding C makes the description incomplete.

Option B:
Option B is incorrect because it groups A, C and D as correct and accepts D. Statement D wrongly implies that ethics and safety can be ignored, but these remain central in science education. Including D invalidates this option.

Option C:
Option C is incorrect because it lists B and C only and ignores A. Statement A is fundamental in defining what virtual labs are, so leaving it out weakens the conceptual explanation.

Option D:
Option D is correct because it brings together A, B and C, the three statements that highlight simulation, safety and access, while rejecting the misleading claim in D.

Statements A, C and D are correct, whereas B is incorrect. A is true because television can show laboratory experiments, field situations or animations that are difficult to arrange in ordinary classrooms. C is true since radio can deliver lessons to geographically remote learners who lack regular access to teachers. D is true because learners need critical media literacy to evaluate the quality and bias of messages. B is false because mass media usually provide limited, indirect or delayed feedback rather than immediate personalised responses from each learner.

Option A:
Option A correctly gathers A, C and D, presenting a balanced view of how media supplement classroom work and why critical viewing is needed. It rejects B, which exaggerates feedback possibilities in mass communication. As it includes all and only the accurate statements, A, C and D only is the correct answer.

Option B:
Option B lists A and C only and omits D, failing to acknowledge the crucial role of critical viewing skills in educational media use. Although A and C are correct, leaving out D makes the description incomplete. Therefore A and C only cannot be accepted.

Option C:
Option C combines C and D, leaving out A and thus ignoring the valuable contribution of television demonstrations. Since A is also a correct statement, C and D only does not contain the full set of correct statements. This option is therefore not valid.

Option D:
Option D treats A, B, C and D as all correct, but B wrongly claims that mass media always allow immediate personalised feedback. Including this false assertion alongside the true statements makes the whole combination unacceptable.
