The ability to detect fine details in light conditions is primarily reliant on cones, which are photoreceptor cells located in the retina. Cones function best in bright light and are responsible for color vision and the perception of high-resolution detail. They allow us to see during daylight and play a crucial role in tasks that require sharp vision, such as reading or recognizing faces.

Cones are concentrated in the fovea, the central part of the macula, which is why this area is so important for our vision. Rods, on the other hand, are more sensitive to low light levels and are responsible for vision in dimly lit environments but do not provide the detail or color discrimination that cones do. While the optic nerve is essential for transmitting visual information from the retina to the brain, it does not play a direct role in detecting light conditions or details.

In summary, cones are essential for detecting fine details in bright light, making them the correct choice in this context.
