Multiple Choice

The fovea is located at the center of the macula.

Explanation:
The fovea centralis sits at the exact center of the macula lutea. It’s a tiny pit where inner retinal layers are displaced so light has a direct path to a dense cluster of cone photoreceptors, giving the highest visual acuity and color vision for central vision. This central placement within the macula explains why the fovea is described as being at the center of the macula. It’s not at the optic nerve head (that’s a different landmark where the blind spot is) and it’s not in the peripheral retina, which is richer in rods and provides less acuity.
