Virtual laboratories in education – UGC NET Question

Statements A, B and C accurately describe how virtual labs extend experimental learning, whereas D is an overstatement. Virtual labs provide simulations and remote access that supplement physical labs and address resource constraints. They also support repeated practice and flexible access, especially in large or distance programmes. Yet, for some skills and disciplines, physical experimentation remains important, so D cannot be accepted as correct.

Option A:
Option A is correct because it selects the three true statements and excludes the extreme claim in D. It recognises virtual labs as powerful complements rather than complete replacements for physical laboratories. This balanced view is aligned with current practices in technology-enabled science education.

Option B:
Option B is incomplete because it includes only A and B and omits C. While A and B are true, statement C about data-logging and anytime access is also a common feature of virtual labs, so the set of correct statements is not fully represented.

Option C:
Option C is incorrect because it combines B and C with D and assumes all three are correct. Although B and C are true, D wrongly asserts that virtual labs make physical labs unnecessary in every discipline, which is not realistic.

Option D:
Option D is incorrect because it treats all four statements as correct and thereby accepts D. Since D conflicts with the complementary role of virtual and physical experimentation, this combination cannot be chosen.
