12.	Which of the following Best explains why It is difficult to see clearly in dim light? A. Initially the eyes cannot operate when the light is dim B. The choroid reflect all the light that enters the eye C. Too little light reaches the retina and so the cones may not be stimulated at all D. Dim light causes the pupil to close up so that not much light enters the eye	C
