Show answer & explanation
Correct answer: D
Sound is a mechanical wave and requires a material medium (solid, liquid, or gas) for its propagation. It travels by transferring vibrations from one particle to another.
In a vacuum, there are no particles present to vibrate and carry the sound energy. Therefore, sound cannot travel through a vacuum.
Since water, air, and an iron rod all contain particles, sound can travel through them. However, sound transmission is not possible in a vacuum.
Hence, the correct answer is Vacuum.
