B. energy

D. all of the above

Waves carry both matter and energy. For example, ocean waves carry both water and energy. Sound waves carry energy and can propagate through various mediums, including air, water, and solids. Electromagnetic waves, such as light, carry energy and can travel through a vacuum, where there is no matter. So, waves can carry a combination of matter, energy, or both.
