D Correct answer
Explanation

Primary waves (P-waves) are longitudinal, compressional seismic waves that push and pull rock in the direction of wave propagation, similar to how sound waves move through air. They are the fastest seismic waves and travel through both solids and liquids, though faster through solids due to higher elasticity. All three statements (A, B, C) are correct.
