Optic Disc
The point in the eye where the optic nerve meets the retina, appearing as a small, circular area.
Pigmented Crescents
Darkened, crescent-shaped areas often found at the margin of the optic disc in the human eye.
Macula
A small central area of the retina responsible for sharp, detailed vision, particularly critical for tasks like reading and driving.

Final Answer :
A
Explanation :
The optic disc is located on the nasal side of the retina. Its color is a creamy yellow-orange to a pink, and the edges are distinct and sharply demarcated, not blurred. A pigmented crescent is black and is due to the accumulation of pigment in the choroid. Presence of pigmented crescents in the macular area is an abnormal finding. A pigmented crescent is black and is due to the accumulation of pigment in the choroid. The optic dish margins are normally distinct and sharply demarcated, not blurred around the edges. The macula is located on the temporal side of the fundus of the eye, not on the nasal side of the retina. The correct answer of a normal finding is that the optic disc is a yellow-orange color.
