Options

A. the angle of refraction is too small to observe
B. light incident upon the glass is partially reflected and this tends to mask the effect of refraction
C. the emergent ray is parallel to the incident ray and only lateral displacement occurs
D. the window pane is too thin for refraction to occur.
