Solution

The correct option is C

retina


Correct Answer- C

  1. The retina is the back tissue layer of the eye.
  2. Millions of light-sensitive cells (rods and cones) and other nerve cells make up the retina, which receives and organizes visual information.
  3. On the retina, true and inverted images are created.
  4. It turns the image into electrical nerve impulses that the brain can perceive.

Explanation for incorrect options

A- The pigmented tissue that surrounds the pupil in the center of the eye. The iris regulates the size of the pupil, allowing more or less light to enter the eye.

B- Ciliary muscles regulate the flow of aqueous humor into Schlemm's canal and govern accommodation for viewing objects at different distances.

D- Pupil allows light into the eye by dilating or constricting. It shrinks in bright light and grows in size as the amount of light drops.

Hence, the correct answer is the option C retina.
