UGC NET Questions (Paper – 1)

Statements A, B and C correctly describe widespread uses of PDF, word processing and audio file formats. PDF preserves layout, docx supports editing and mp3 or wav are standard for audio. Statement D is false because different formats often require specialised applications and may face compatibility limits. Thus, the correct combination is A, B and C only.

Option A:
Option A is incorrect because it lists only A and B as correct and omits C. While A and B are true, statement C is also correct and reflects basic knowledge of audio storage. Excluding C gives a partial view of file formats.

Option B:
Option B is incorrect because it includes A, B and D as correct, thereby accepting D. Statement D ignores real-world compatibility issues, so it cannot be treated as true.

Option C:
Option C is correct because it recognises that PDF, docx and mp3 or wav each serve different but accurately described roles. It rejects the unrealistic claim in D that a single application can handle all formats without problems.

Option D:
Option D is incorrect because it groups B, C and D only as correct statements. While B and C are valid, D is not, and the omission of A further weakens this combination.

Statements A, B and C correctly describe how format choices influence document sharing, while D is incorrect. PDFs are widely used for fixed-layout sharing, proprietary formats may lock users into particular software and choosing common formats helps recipients open files easily. Claiming that format choice has no impact ignores practical issues like missing software or different versions. Therefore, the combination including A, B and C but excluding D is correct.

Option A:
Option A is incomplete because it lists only A and B and omits C. Although the roles of PDF and proprietary formats are important, explicitly stating that common formats aid compatibility adds a crucial practical point for communication.

Option B:
Option B is incorrect because it includes A, B and D and thereby accepts D. Since D denies the role of format choice in access problems, this combination conflicts with everyday ICT experience where incompatible file types often cause difficulties.

Option C:
Option C is correct because it brings together the three statements that highlight layout preservation, software dependence and deliberate choice of widely supported formats. Excluding D avoids the misleading claim that format choice is irrelevant.

Option D:
Option D is incomplete because it groups B and C only and leaves out A. Statement A explains why PDF is so commonly recommended, so its omission makes the picture of file formats less complete.
