Answer: (B)

Verified step by step guidance

1. Begin by understanding the structure of the human retina, which is a layer of tissue at the back of the eye responsible for receiving light and converting it into neural signals.
2. Identify the main types of cells involved in the process of phototransduction, which is the conversion of light into electrical signals. These cells are known as photoreceptors.
3. Recognize that there are two primary types of photoreceptors in the human retina: rods and cones. These cells are specialized for different functions in vision.
4. Rods are responsible for vision in low light conditions and do not detect color. They are more numerous and are located primarily in the peripheral regions of the retina.
5. Cones are responsible for color vision and are concentrated in the central part of the retina, particularly in the fovea, which is the area of highest visual acuity.
