Which from the following is true for “Sound”?

Sound cannot travel through a vacuum. Sound is a mechanical wave and hence requires a physical medium to propagate. Sound propagates by jerking particles, which can be atoms or molecules, of the medium it is passing through. In space, there is no medium to carry out this jerking, and hence sound cannot propagate.
