Cones are responsible for the perception of color and the sharp focus of details. They are concentrated in the central part of the retina and are responsible for high visual acuity. Rods, not cones, play a key role in night vision, while the statement about cones being thin, cylindrical receptor cells is incorrect. Additionally, while cones do contribute to peripheral vision, this is primarily the role of the rods, so choice D is also incorrect.
