UGC NET Questions (Paper – 1)

Statements A, B and D capture good technical practices in video-based teaching, whereas C is unsafe and false. Muting, reliable connectivity and screen sharing all contribute to effective sessions. Posting meeting links publicly increases the risk of unauthorised access and disruptions, thus reducing security. Therefore, the correct combination is A, B and D only.

Option A:
Option A is incomplete because it selects only A and B and omits D. While audio quality and bandwidth are important, screen sharing is also a widely used instructional feature that should be recognised.

Option B:
Option B is correct because it assembles all three true statements and excludes C, which conflicts with basic security guidelines for online meetings. It reflects both technical and security considerations in ICT-based teaching.

Option C:
Option C is incorrect because it groups B and C as correct and leaves out A. Statement C is wrong and should not be included, while A is a practical behaviour that significantly improves class quality.

Option D:
Option D is incorrect because it mixes A and D with C and accepts C. Since public sharing of links undermines security, this combination cannot be accepted as correct.
