Question

Following is the diagram of an eye. Match the labelled parts (A - J) with their functions given below and select the correct option.

(i) Carries nerve signals to the brain
(ii) Regulates the size of the pupil to let more or less light into the eye
(iii) Changes the shape of the lens
(iv) Photoreceptors are concentrated at this point

• A. (i) - B, (ii) - D, (iii) - F, (iv) - H
• B. (i) - J, (ii) - G, (iii) - I, (iv) - C
• C. (i) - A, (ii) - C, (iii) - E, (iv) - G
• D. (i) - G, (ii) - D, (iii) - C, (iv) - E

Answer 1

The correct option is D (i) - G, (ii) - D, (iii) - C, (iv) - E

Optic nerve carries the nerve signal to the brain.

Iris regulates the size of the pupil to let more or less light into the eye.

Ciliary muscle changes the shape to adjust for objects at different distances.

Photoreceptors are concentrated at the fovea of the eye.

So, option D is the correct option.
