Which is not a refractive medium of eye

Which one of the following is NOT a refractive medium of the eye?

The speed of light in a medium is high if the refractive index of the medium is ……. .

A ray of light, after passing through a medium, meets the surface separating the medium from air at an angle of 45^(@) and is just not refracted. What is the refractive index of the medium?

The refractive index of a medium (2) with respect to medium (1) is x and refractive index of medium (2) with respect to medium (3) is 'y' then what is the refractive to index of the medium (3) with respect to medium (1).

State the factors on which refractive index of a medium depend ?
