Sound waves can be easily diffracted by any obstacles.
Grace observed that ocean waves continue to splash onto the shore yet the beach is not completely submerged nor the middle of the ocean is depleted of its water. Which of the following statements can explain the phenomenon observed by Grace?

A. Waves coming from the other bodies of water carry a sufficient amount of water to avoid.

B. The water waves carried to the shore will eventually go back to the ocean by passing through underground ducts.

C. Waves don't actually move the water in the middle of the ocean to the shore; they simply transfer their energy from one place to another.

D. The water from the underground sources finds its way through the vents lying in the ocean floor supplying enough water to prevent water loss.
