The choice of cones as the correct answer is based on their specific function in the visual system. Cones are photoreceptor cells located in the retina that are highly sensitive to bright light and play a crucial role in color vision. Unlike rods, which are more sensitive in low-light conditions and primarily responsible for peripheral and night vision, cones are essential for visual acuity and the perception of fine detail in well-lit environments.

In the retina, cones are concentrated in the fovea, the central part of the retina where vision is sharpest. They come in three types, each sensitive to different wavelengths of light, corresponding to short (blue), medium (green), and long (red) wavelengths. This allows for the perception of a wide range of colors, making them vital for tasks that require detailed visual input, like reading and recognizing faces.

The other cells mentioned support various aspects of vision. Ganglion cells process visual information and transmit it to the brain, but they do not directly capture light. Rods are specialized for vision in dim light and do not contribute significantly to color perception. Photoreceptors is a broader term that encompasses both rods and cones, but within the context of the question, cones specifically address the aspect of central vision and color
