Retina houses light-sensitive photoreceptors

Steps:

• Recall that the human eye's horizontal section includes structures like cornea, lens, retina, and optic nerve.
• Identify receptor cells: rods and cones detect light and are located in the innermost layer at the eye's posterior.
• Match to diagram: the curved, layered region at the back corresponds to the retina.
• Confirm: no other part contains these specialized cells.

Why B is correct:

• The retina contains photoreceptor cells (rods for low light, cones for color) that convert light into neural signals, per basic eye anatomy.

Why the others are wrong:

• A (cornea): Transparent outer layer for light refraction, lacks receptors.
• C (lens): Focuses light onto retina, no sensory cells.
• D (optic nerve): Transmits signals from retina to brain, no light detection.

Final answer: B
