• A. Vitreous humor
• B. Aqueous humor
• C. Retina
• D. Sclera

Answer: (A)

Vitreous humor is the soft, jelly-like substance that fills the vitreous chamber behind the lens. It helps keep the eyeball’s shape by filling the space and by pressing the retina gently against the choroid, maintaining proper optical alignment. Aqueous humor sits in the anterior segment, nourishing avascular structures and helping regulate intraocular pressure, so it doesn’t fill the posterior chamber. The retina is the light-sensitive tissue at the back of the eye, and the sclera is the eye’s tough outer coat.
