Answer

Correct option: D.
All of the above
Vitreous humour is a clear gelatinous gel like fluid that fills the space between the lens and the retina.
It helps in maintaining the shape of the retina by holding the retina in its place.
The crystalline lens helps in finer adjustments of focal length required to focus objects at different distances and forms an inverted real image of the object on the retina.
Aqueous humour is present between the lens and the cornea and helps in maintaining the pressure in the eye.
