Solution

The correct option is B It is more in solid state as compared to the gaseous state.
Sound wave travels fastest in solids, faster in liquids and slower in gases.
Temperature is the average kinetic energy of all the particles of a body. When the temperature increases for a given state of matter, the movement of particles increases and so does the speed of sound.
