Answer:
D. P waves move straight through all medium and S waves move only through solids in a curvy motion
Explanation:
The first kind of wave that is mentioned here is the P wave. This is also called the primary wave. This type of wave can move through solid rock and fluids. Because of this, this is the wave that arrives first at a seismic station. These are compressional waves. On the other hand, S waves are the second type of wave that you feel in an earthquake. These are slower and do not move through liquid mediums.
