The nasal hemiretina contains more rods than the temporal hemiretina. This is because the nasal hemiretina is responsible for peripheral vision, which relies more on rods for low light and peripheral vision detection. The fovea, on the other hand, is densely packed with cones and has very few rods, making option A incorrect.
