What are the two major components of the retina?

• A. Rods and Cones (Night and Day)
• B. Cones (Day Vision) and Rods (Night Vision)
• C. Rods Only
• D. Cones Only

Answer: (B)

Two main photoreceptor types in the retina are rods and cones. Rods are highly sensitive in low light and provide night vision without color, while cones require brighter light to give color vision and fine detail for day vision. The option that pairs cones with day vision and rods with night vision directly reflects these distinct roles, making it the best choice. The other options miss one component or describe the roles less precisely.
