• A. Iris
• B. Cornea
• C. Lens
• D. Aqueous humor

Answer: (B)

The cornea is the clear, curved tissue that forms the outer front surface of the eye, covering the iris and pupil. It is transparent to let light pass through and provides most of the eye’s refractive power as light enters. The iris is the colored part that controls how much light enters by adjusting the pupil; the lens sits behind the pupil and fine-tunes focus; the aqueous humor is the clear fluid in the anterior chamber between the cornea and the iris. So, the clear tissue covering the front of the eye is the cornea.
