Solution
The correct option is D Carbon dioxide
The velocity of sound is the distance travelled per unit time by a sound wave as it propagates through an elastic medium. Carbon dioxide is more dense than air ( at the same temperature and pressure ), because the individual particles are on average more massive, not because they are close together. They move very slowly for a given kinetic energy. Hence the velocity of sound is minimum in carbon dioxide.
