Common ICT file formats – UGC NET Question

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.
