The correct answer is option (c) that is glass.

Reason -
●We know that the sound travels at fast rate in solids than liquid, gas and vacuum.

●We also know that the sound travels at faster rate in denser medium. The density of solid is greater than the density of liquid,gas and vacuum.

Velocity of sound in-:
Solid > Liquid > Gas > Vacuum

●Hence the velocity of sound is highest in the glass,that is Option (c)
