The incoming ray enters the ice crystal through one face and refracts towards the normal because the index of refraction inside the crystal is greater than the index of refraction outside. The refracted ray then crosses parallel planes at different angles, leading to further refraction and reflection. The outgoing ray that follows this path is option C. The other options do not follow the laws of refraction and reflection.
