The correct statement that explains how rods and cones work to help us see things is:
Rods detect light; cones detect color; and the brain decomposes the color into green, blue, and red.
This is because rods are primarily responsible for vision in low light conditions and do not detect color, while cones are responsible for color vision and operate best in bright light. The brain processes the signals from the cones to perceive different colors based on combinations of the primary colors (red, green, and blue).
