Step 1
What is the defect and which lens could be used to correct it?
Answer
The diagram shows an eye defect, specifically short-sightedness (myopia). In myopia, light rays entering the eye are focused in front of the retina. To correct this defect, a convex lens is required, which helps to diverge the light rays and extend the focus to the retina. Therefore, the correct answer is:
B) Long-sightedness, corrected with a convex lens.
