They will slow down.
Reason: For (A) a decrease in temperature (for a gas) lowers the speed of sound (c ∝ √T). For (B) sound generally travels much faster in liquids than in gases (c = √(bulk modulus/density)), so going from liquid to gas reduces the wave speed. The other choices describe temporary pressure/density oscillations (not a net change in medium density), so they are incorrect.
