The correct answer is (B) they travel faster than S waves
As the interior of the earth is incompressible, the P-waves moves much faster and transmit their energy through the medium and travel very fast as compared to the S waves. In case of S waves, they are slow because the movement of medium is perpendicular to the direction of propagation of waves’ waves travel 60 times faster than S waves. The variation in speed of travel is because the earth reacts differently to both the waves.
