D Correct answer
Explanation

Sound travels fastest in solids (highest speed), then liquids, and slowest in gases. This is because sound speed depends on how closely particles are packed and how quickly they can transfer vibrations. Solids have the densest packing and strongest bonds, enabling fastest sound propagation.
