Answer: (A)

Verified step by step guidance

1. Step 1: Begin by identifying the accessory eye structures listed in the problem: Vitreous humor, Lacrimal glands, Ciliary body, and Conjunctiva.
2. Step 2: Understand the function of each accessory eye structure. The vitreous humor is a gel-like substance that helps maintain the eye's shape and provides a medium for light transmission, but it does not nourish the cornea.
3. Step 3: Review the function of the lacrimal glands. They are responsible for producing tears, which help lubricate the eye and provide nutrients to the cornea.
4. Step 4: Examine the role of the ciliary body. It is involved in controlling the shape of the lens, allowing the eye to focus on objects at different distances.
5. Step 5: Consider the function of the conjunctiva. It is a membrane that covers the eye surface and provides protection against foreign particles and infections.
