Answer is option (d) Solid, liquid and gas.
Sound travels more quickly through solids than through liquids and gases because the molecules of a solid are closer together and, therefore,can transmit the vibrations (energy) faster. Sound travels most slowly through gases because the molecules of a gas are the farthest apart. In a vacuum sound cannot travel because there is no matter for it to move through. Sound travels as waves, which are vibrating particles. Sound waves are reflected by surfaces. It is a type of energy made by vibrations. When any object vibrates, it causes movement in the air particles.
