Which one of the following statements about progressive mechanical waves is correct?
(a) In transverse waves, particle displacement is parallel to the wave direction, whereas in longitudinal waves it is perpendicular.
(b) Both transverse and longitudinal waves carry energy without transporting matter from one place to another.
(c) Transverse mechanical waves can propagate in vacuum because their oscillations are perpendicular to the direction of travel.
(d) Only longitudinal waves can travel through solids, liquids and gases; transverse waves can travel through gases alone.
