A. Fovea - III. Point of greatest visual acuity or resolution
The fovea is a small depression in the retina of the eye that contains a high concentration of cone cells, which are responsible for detailed and color vision. It is the area of the retina with the highest visual acuity.

B. Iris - I. Visible colored portion of the eye that regulates the diameter of the pupil
The iris is the colored part of the eye surrounding the pupil. It controls the size of the pupil and regulates the amount of light entering the eye.

C. Blind spot - IV. Leaves the eyeball, and photoreceptor cells are absent
The blind spot, also known as the optic disc, is the area on the retina where the optic nerve leaves the eye. It does not contain photoreceptor cells, so there is no vision in that particular area.

D. Sclera - II. External layer of the eye formed of dense connective tissue
The sclera is the tough, white, outer layer of the eye that forms the protective covering of the eyeball. It is composed of dense connective tissue.

Therefore, the correct matching is:
A–III, B–I, C–IV, D–II, which corresponds to Option 1.
