Answer: (B)

Verified step by step guidance

1. Understand the structure of the eye: The eye is composed of several parts, each with a specific function. The main parts include the cornea, lens, iris, and retina.
2. Identify the function of each part: The cornea is the transparent front part of the eye that covers the iris and pupil. The lens focuses light onto the retina. The iris controls the size of the pupil and thus the amount of light entering the eye.
3. Focus on the retina: The retina is a layer at the back of the eye that contains cells sensitive to light. It is crucial for converting light into neural signals.
4. Learn about photoreceptors: The retina contains two types of photoreceptors, rods and cones. Rods are responsible for vision in low light conditions, while cones are responsible for color vision and detail.
5. Conclude the identification: Since rods and cones are located in the retina, the part of the eye that contains these photoreceptors is the retina.
