Answer:

a. All of these statements are true

Explanation:

The fovea is a region of the retina that’s densely packed with cones, a type of photoreceptor (a cell that detects light). The other type of photoreceptor is the rod.  

While rods function at low light levels and allow night vision, they can’t distinguish color. In contrast, cones function at high light levels and provide color vision.  

That's why you can't perfectly distinguish colors in a dark place.
