B. LONGITUDINAL WAVES
These are mechanical waves in which matter in the medium moves forward and backward along the same direction that the wave travels.
Note: Longitudinal Waves and Compressional Waves are the same. Some people research it and what they see is "Compressional Waves", but longitudinal waves and compressional waves are the same.
