Answer:
B. P waves travel through solids and liquids. S waves travel through solids.
Explanation:
S waves cannot pass through the liquid outer core, but P waves can. The waves are refracted as they travel through the Earth due to a change in density of the medium. This causes the waves to travel in curved paths
