Best choice (from the given options): "The speed of sound is generally faster in solids than in gases, because solids are denser than gases."

Clarification: the conclusion (sound is faster in solids) is correct, but the real reason is that solids are much more rigid (have a much larger elastic modulus) — v ≈ sqrt(elastic modulus / density) — so the large stiffness of solids more than offsets their higher density.
