Explanation
The spot where the optic nerve connects to the retina lacks rods and cones and is thus called the blind spot. Choices B and C are distracter items and are not true. Floating debris and retinal damage could cause blind spots. However, these do not occur in everyone, and the question implies the blind spot present in everyone’s eyes.
