Why do humans perceive faint light better in the periphery of the eye?

    a.    The fovea is closer to the retina's blind spot than peripheral receptors are.
    b.    Ganglion cells in the periphery transmit their information to a larger brain area.
    *c.    More receptors in the periphery than in the fovea funnel input to each ganglion cell.
    d.    Receptors in the periphery are closer to the pupil.
