A. Pupil
B. Nail
C. Cornea
D. Hair

Check Answer

The correct answer is C) Cornea.

The cornea is the clear outermost layer that covers the front of the eye. It is the main refracting surface of the eye and helps to focus light on the retina. Unlike most other tissues in the body, the cornea does not have any blood vessels running through it. Instead, it gets its oxygen and nutrients directly from the tear film and the aqueous humor, a clear fluid that fills the space between the cornea and the iris. This lack of blood vessels is important to maintain the clarity of the cornea, as blood vessels can cause scattering of light and interfere with vision.
