About this MCQ
This Medium Everyday Science MCQ checks one syllabus fact. Candidates use it for NTS GAT General, PPSC Lecturer practice.
The question is: “Sound cannot travel through:”
The accepted answer is C. Vacuum. Sound requires a material medium (solid, liquid, or gas) to propagate. In a vacuum there are no particles to transmit vibrations, so sound cannot travel.

Why not A: Sound travels through air as longitudinal waves.
- B. Water
Why not B: Sound travels faster in water than in air.
- C. Vacuum ✓
- D. Steel
Why not D: Sound travels very fast through solids like steel.
