Primary waves (P-waves) are compressional waves and are the fastest type of seismic wave. They can travel through all states of matter: solid, liquid, and gas. Statement B claims they can travel *only* through solid materials, which is incorrect as they also pass through liquids and gases.

– Earthquake waves are mainly of two types: Body waves (P and S waves) and Surface waves (Love and Rayleigh waves).
– P-waves are primary waves, S-waves are secondary waves.

P-waves are similar to sound waves (longitudinal waves). S-waves (shear waves) can only travel through solid materials because they involve particle motion perpendicular to the direction of wave propagation, which is not supported in fluids (liquids and gases). P-waves arrive first at a seismic station because they are faster than S-waves and surface waves.
