A student traces the path of a ray through a glass prism for four different values of angle of incidence. On analysing the diagrams he is likely to conclude that the emergent ray
A. is always parallel to the incident ray.
B. is always perpendicular to the incident ray.
C. is always parallel to the refracted ray.
D. always bends at an angle to the direction of incident ray.
