Concept:Sound waves are mechanical waves that require a material medium for transmission.
Explanation:Sound travels by vibrating the particles of a medium.
It can pass through gases such as air, through liquids, and through solids.
Particles in all three states of matter are able to transfer these vibrations.
Thus, sound waves are transmitted in air, liquids, and solids.
In general, sound travels fastest in solids, then liquids, and slowest in gases.
This means all the listed media, I, II, and III, allow sound wave transmission.
Answer:D. I, II & III
