The best example of using sensory details to help the reader visualize the tsunami is:
C. If you are lucky, you see the tsunami before you hear it; a solid mass of inky ocean builds up into a wall out at sea. It sucks greedily at the water at the shoreline, leaving silvery fish flapping weakly in shallow pools.
This sentence incorporates visual imagery ("solid mass of inky ocean," "a wall out at sea"), auditory imagery ("you hear it"), and tactile elements ("sucks greedily"), creating a vivid and immersive description of the tsunami experience.
