Answer
- A The rods
Explanation
The cones work in bright light and provide colour vision and sharp vision; they are concentrated in the fovea. The rods are much more sensitive to light but see no colours and only blurred images. They lie at the edge of the retina, which is why faint lights are seen better at night by looking slightly to the side.
