Show answer & explanation
Correct answer: C
When a person moves from bright sunlight to a dark room, the eyes need to adjust to the lower light levels. The iris muscles relax, causing the pupil (the opening in the center of the eye) to dilate or increase in size. This allows more light to enter the eye, enabling better vision in the dark environment.
