Answer

Answer:

C. seismic waves cannot travel through liquids.

Brief Explanations:

The shadow zone is due to S - waves being unable to travel through the liquid outer core of the Earth. P - waves can travel through both solids and liquids but are refracted at the boundary between the mantle and the core, creating the shadow zone. S - waves are transverse and require a rigid medium, so they stop at the liquid outer - core, contributing to the shadow zone phenomenon.
