Which set comprises the structures of the eye?

• A. Cornea, pupil, iris, lens, retina
• B. Ear parts only
• C. Brain lobes
• D. Skin and hair

Answer: (A)

Understanding the structures that make up the eye: the cornea is the clear front surface that helps bend light, the pupil is the opening whose size is regulated by the iris, the iris gives the eye its color and controls how much light enters, the lens sits behind the pupil to fine-tune focus onto the retina, and the retina contains light-sensing cells that convert light into neural signals for the brain. These are the actual parts of the eye involved in vision, so this set correctly represents eye structures. The other options describe parts of other systems: ear parts belong to hearing and balance, brain lobes are brain structures, and skin and hair are part of the skin/integumentary system, not the eye.
