What is true about the structure of the eye?A) Pupil is a layer at the back of the retina containing enzymes to regenerate visual pigments.B) Vitreous humor is the liquid in the eyeballsC) Lens is where the eyes are located in the skullD) Six extraocular muscles is a layer at the back of the eye containing neuronsE) The retina is a white part of the eye.

B) Vitreous humor is the liquid in the eyeballs - This statement is true. The vitreous humor is a clear, jelly-like substance that fills the space in the middle of the eyeball. It helps to maintain the shape of the eye and also helps to transmit light to the retina.

The other statements are not accurate:

A) The pupil is not a layer at the back of the retina. It is actually a hole located in the center of the iris of the eye that allows light to strike the retina.

C) The lens is not where the eyes are located in the skull. It is a part of the eye itself that focuses light onto the retina to create clear images.

D) The six extraocular muscles are not a layer at the back of the eye. They are muscles that control the movements of the eye.

E) The retina is not the white part of the eye. It is a thin layer of tissue at the back of the eye that contains millions of light-sensitive cells and other nerve cells that receive and organize visual information. The white part of the eye is called the sclera.
