Your answer: —  ·  Correct: C
Explanation

In eye donation the cornea — the thin, transparent front layer of the eyeball located in front of the iris — is the tissue utilised for transplantation. Official eye‑banking guidance states that only the cornea (the transparent layer in front of the iris) is used for transplant procedures [1]. Anatomical descriptions note that the cornea forms the transparent bulge on the eye’s front surface and provides most of the eye’s refractive power, making it the critical structure for restoring vision when damaged [2]. Donated corneas can restore sight to people with corneal blindness; one pair of donated eyes can provide corneal tissue to multiple recipients, highlighting the cornea’s central role in eye donation programs [4].
