The correct option is B outer surface of the cornea
The explanation of the correct option:
In the case of option B,
- The transparent, spherical part of the cornea that surrounds the iris and pupil is known as the cornea.
- When light rays pass through the eye's curved, transparent front surface, the majority of refraction takes place (cornea).
- Light rays are also bent by the natural (crystalline) lens of the eye.
- When an item passes in front of the eye, its rays pass through this transparent cornea and enter the eye.
- The outer surface is where this refraction takes place.
The explanation for incorrect options:
In the case of option A,
The cornea and the clear, biconvex crystalline lens of the eye work together to assist refract light so that it is focused on the retina. only of images are formed on a crystalline lens.
In the case of option C,
The iris is a thin, pigmented layer that controls how much light may reach the retina. It also determines the color of the eyes.
In the case of option D,
The tiny black circle in the iris's middle is the pupil. Over the lens, there is a tiny opening through which light enters the eye and is focused on the retina to generate images.
The cornea develops a transparent protrusion on the front surface of the eyeball as light rays enter the eye through a thin membrane. The outer surface of the cornea is where most of the refraction of light rays entering the eye takes place.
Therefore, the correct option is B.
