Neither P nor S waves

Detailed explanation-1: -Option B) Secondary Waves – These are also called S-waves and are transverse in nature. They are slower than P-waves. These waves can only travel through solids. They cannot travel through liquids and gases as they cannot support shear stress.
Detailed explanation-2: -P waves can travel through liquid and solids and gases, while S waves only travel through solids. Scientists use this information to help them determine the structure of Earth.
Detailed explanation-3: -There are two types of body waves: P-waves travel fastest and through solids, liquids, and gases; S-waves only travel through solids. Surface waves are the slowest, but they do the most damage in an earthquake.
Detailed explanation-4: -Seismic waves are waves that travel through or over Earth. They are usually generated by movements of the Earth’s tectonic plates (earthquakes) but may also be caused by explosions, volcanoes and landslides.
Detailed explanation-5: -S-waves look like they are traveling perpendicular to the explosion or earthquake. Now, the bond strength in solids versus liquids and gasses explain why s-waves can only travel through solids.
