According to Cortical Magnification in V1, What Is the Reason

According to cortical magnification in V1, what is the reason that leads to a greater amount of cortical territory devoted to the central part of the visual field than the amount devoted to the periphery?

A) The fovea has a very high density of retinal ganglion cells, with small receptive fields, while the density of RGCs declines rapidly with distance from the fovea.
B) The neurons in this pathway are specialized for transmitting information about the form and color of objects in the visual field.
C) The density of RGCs increases rapidly with distance from the central part of the visual field.
D) The areas of the visual cortex differ according to the other areas in the brain from which they receive signals or to which they send signals.
