• A. Aqueous humor
• B. Choroid coat
• C. Cornea
• D. Iris

Answer: (A)

The fluid filling the front part of the eye between the cornea and the lens is the aqueous humor. This clear, watery fluid fills the anterior and posterior chambers, produced by the ciliary processes, circulating around the iris and lens, and draining out via the trabecular meshwork into Schlemm's canal. It nourishes the cornea and lens and helps maintain intraocular pressure. The other structures listed are not fluids in that space: the choroid coat is a vascular layer at the back of the eye, the cornea is the transparent front window, and the iris is the colored part that controls pupil size.
