C) rods; lower
D) cones; lower
Absolute Threshold
The minimum level of stimulus intensity needed for a person to detect its presence at least half the time.
Color Vision
The ability of the eye and brain to perceive differences in wavelengths of light as differing colors.
Light Intensity

Final Answer :
B
Explanation :
Cones are responsible for color vision and have a higher absolute threshold for brightness than rods, meaning they require more light to function effectively. In low light conditions, cones are less effective, making it difficult to distinguish colors.
