The correct answer for this question is option A i.e Body waves.
Body waves are actually S waves which are a kind of Shock waves. They are sent out when an earthquake happens. They are similar to water waves but do not involve any electromagnetic field.
S waves are shear waves and travel at around 6,500 miles per hour. These Body waves can travel through the interior of the earth including the earth's mantle. Since they travel through the interior of the earth, they are used to find an Earthquake's epicenter.
