Answer:(a) Both Statement-I and Statement-II are correct.

Statement-I: P waves (Primary waves) vibrate in the same direction as the direction of wave propagation. They are compressional waves that cause particles to move back and forth parallel to the direction of the wave.

Statement-II: S waves (Shear waves) vibrate perpendicular to the direction of wave propagation. They are transverse waves that cause particles to move in a perpendicular direction to the wave.

Both statements accurately describe the characteristics of P waves and S waves, respectively.
