Cones are responsible for which aspect of vision?

• A. Daytime vision and colour perception
• B. Night vision in dim light
• C. Peripheral vision in daylight
• D. Motion detection in daylight

Answer: (A)

Cones enable daytime vision and color perception because they require bright light, provide high-resolution central vision, and come in three types sensitive to different wavelengths that the brain combines to produce color. In well-lit conditions, cones dominate central (foveal) vision, giving sharp detail and the ability to distinguish colors. By contrast, rods handle night vision in dim light with greater sensitivity but much lower visual acuity and no color information, and peripheral or motion-related processing involves different neural pathways that are not the defining role of cones.
