Approximate Extension of the shadow zone of S-wave is-

Correct option is A

The shadow zone is a region on Earth's surface where seismographs do not record direct P waves or S waves generated by an earthquake.
This zone lies between angular distances of 105° to 145° from the earthquake's epicenter.
The shadow zone forms because S waves are completely absorbed by the Earth's liquid outer core, as they cannot travel through liquids.
S waves, also known as secondary seismic waves, are transverse waves, meaning their particle motion is perpendicular to the wave's direction of propagation.
