Correct answer: A. Nyctalopia
- A. Nyctalopia

- C. Hyperopia
- D. All of the above

Nyctalopia, or night blindness, is difficulty seeing in dim light and is commonly associated with inadequate vitamin A or impaired rod-cell function. Students may choose myopia or hyperopia because both affect vision, but they are focusing defects rather than inability to see at night.
