The pupil is the:
A) colored part of the eye
B) opening in the center of the iris.
C) white of the eye.
D) lining in the back of the eyeball.
Answer: B
Rationale: Light enters the eye through the cornea and passes through an opening called the pupil. The pupil regulates the amount of light that enters by changing its size; it dilates to allow more light to enter and constricts to allow less. The iris is actually a round muscle that adjusts the size of the pupil, and is also what gives your eyes their characteristic color.
