Answer:
The correct answer is B. Cones require bright light in order to distinguish colors.
Explanation:
Cones are the eye cells responsible for color vision. It is believed that there are three types of cones, sensitive to red, green and blue, respectively. Given their form of connection to the nerve endings that are directed to the brain, they are responsible for the spatial definition. They are also little sensitive to light intensity and provide photopic vision (vision at high levels).
