Answer: Option ‘D’ is the correct option as sound journeys more rapidly through solid components than through gases and liquid as the particles of solid are tighter together, so, it can communicate the vibrations (or energy) quicker. Sound journeys most sluggishly through the gas as the particles of gas seem the farthest separately. Inside a vacuum, the sound could not travel for the reason that there are no matters for the vacuum to transfer through. Sound journeys like waves, which is a vibrating particle.
