b. slowest seismic waves; arrive second
c. fastest seismic waves; arrive first
d. point of origin deep in the crust

Explanation:

• P waves: These are primary waves and are the fastest seismic waves, so they arrive first.
• S waves: Secondary waves, slower than P waves, so they arrive second.
• Epicenter: It is the location on the surface above the origin (focus) with the strongest shaking.
• Focus: The point of origin deep in the crust where the earthquake starts.

Answer:

1. P waves - c. Fastest seismic waves, arrive first
2. S waves - b. Slowest seismic waves, arrive second
3. Epicenter - a. Location on surface above the origin with strongest shaking
4. Focus - d. Point of origin deep in the crust
