(B) Sound waves are mechanical waves that require a medium to propagate. In air,the particles of the medium oscillate back and forth in the same direction as the wave propagation. This type of wave motion,where the displacement of the medium is parallel to the direction of wave travel,is defined as a longitudinal wave. Therefore,sound waves in air are longitudinal.
