Solution

The correct option is B Cell a is cone cell more concentrated in fovea centralis
The shape of the outer segment of cones (cell-A) is conical. Cones are present primarily in the fovea centralis and are stimulated by bright light and are responsible for color perception. Mostly, rods (cell-B) are narrower and longer than cones. Rods are light-sensitive cells that lack color discrimination and are almost exclusively present at the outermost edges of the retina.
The correct answer is B.
