Kerat(o) refers to which structure?

Explanation:
Kerat/o designates horn-like tissue, and in medical language it most often refers to the cornea, the clear front surface of the eye. That connection is why the cornea is the best match for this root, as you see in terms like keratitis (inflammation of the cornea) and keratoplasty (corneal transplant). The other options point to different roots—milk (lact/o), abdominal area (abdomin/o or ventr/o), and yellow (xantho-/cirrh/o)—which don’t relate to the cornea.
