Solution

The correct option is C Sound is a form of energy.
Sound is a form of energy propagated in the form of waves (vibrations). Sound can travel in all kinds of material media like solids, liquids, and gases. Sound needs a medium to travel and hence, cannot travel in vacuum (space). However, light travels much faster than sound in any medium.
