Option (C) is correct because the textbook explicitly states that 'The surface waves are the last to report on seismograph. These waves are more destructive.' Additionally, the context mentions that 'Surface waves are considered to be the most damaging waves.' The surface waves cause displacement of rocks, leading to the collapse of structures. In contrast, P-waves and S-waves are body waves that travel through the interior of the earth, and while S-waves can cause damage, surface waves are explicitly identified as the most destructive in the NCERT text.
