Correct option: CExplanation:The retina is the innermost layer of the eye and is responsible for sight.It is connected to the brain with the help of the optic nerve.The outermost layer of cells is the photoreceptor cells that detect light and low light vision.Next to them are the bipolar cells that perceive the signal.Innermost is the ganglionic cells that form the optic nerve and transmit information.Hence, the order of three layers of cells in the retina of the human eye from inside to outside is "Ganglion cells, bipolar cells, photoreceptor cells".
