C) cornea ? aqueous humor ? vitreous body ? lens ? conjunctiva ? choroids ? retina
D) conjunctiva ? cornea ? lens ? aqueous humor ? vitreous body ? retina
E) cornea ? aqueous humor ? conjunctiva ? lens ? vitreous body ? retina ? choroid

Accepted Answer

The correct sequence for a ray of light entering the eye is: conjunctiva (the outermost layer), cornea (the clear front surface of the eye), aqueous humor (the fluid in the front part of the eye), lens (focuses light onto the retina), vitreous body (the clear gel that fills the space between the lens and the retina), and finally the retina (where light is converted into neural signals for the brain).
