• D. becomes larger, remains the same

Answer 1

The correct option is B becomes larger, becomes smaller


The size of our pupil keeps changing according to the lighting conditions around us. If we're in a bright environment, the pupil will shrink in size to allow less light to enter the eye. In dark surroundings, the pupil expands to let more light in. This self-adjustment of the size of the pupil allows us to see objects around us clearly in different lighting conditions.
