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.

Detailed explanation-2: -There are two types of body waves: P-waves travel fastest and through solids, liquids, and gases; S-waves only travel through solids.

Detailed explanation-3: -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-4: -S waves are called secondary waves because they always arrive after P waves at seismic recording stations. Unlike P waves, S waves can travel only through solid materials. After both P and S waves have moved through the body of Earth, they are followed by surface waves, which travel along Earth’s surface.

Detailed explanation-5: -Rayleigh waves move in a backward-rotating motion and cause both vertical and horizontal motion. P waves are able to travel through both solid rock (such as granite) and liquid material (such as volcanic magma or water), while S waves are only able to travel through solid rock.
