Solution
The correct option is B Hypermetropia
The defect corrected here is Hypermetropia or far-sightedness. In Hypermetropia, light rays from nearby objects are focused by the eye-lens at a point behind the retina. To correct this defect, a convex lens of appropriate power is used. The presence of this convex lens helps the light rays to get focused on the retina.
