what types of waves are sound waves?

Your answer would be D. Mechanical and Pressure/Longitudinal. This is because a sound wave is usually a type of pressure wave caused by the vibration of an object in a conductive medium such as air. These waves are also mechanical because they require a medium to travel through. This is also why sound simply cannot travel through vacuums like space, because they have no mediums in which sound can travel through.
