Correct answer: C

Option A: This statement is incorrect. The cornea is a transparent, avascular layer at the front of the eye that covers the iris, pupil, and anterior chamber.

Option B: This statement is partially correct. The cornea is made up of a dense matrix of collagen fibers, but it is not the most sensitive portion of the eye. The most sensitive part of the eye is the conjunctiva, which is the thin, transparent layer that covers the white part of the eye and the inner surfaces of the eyelids.

Option C: This statement is correct. The cornea is an external, transparent, and protective proteinaceous covering of the eye-ball.

Option D: This statement is incorrect. The cornea is composed of dense connective tissue of collagen and cannot repair itself. Any injury to the cornea may result in permanent scarring or loss of vision.
